Version 5.0.51 (Released August 9, 2010)

Feature: Native 64-bit support (in addition to the existing 32-bit support) dramatically increases the scalability of FolderSizes within enterprise environments. Note that running the 64-bit version of FolderSizes requires a 64-bit processor and Windows operating system.
Feature: Overall performance has been greatly enhanced. Core analytical and thread models have been re-engineered for improved performance.
Feature: A completely overhauled in-memory database model provides superior tracking of all file system objects that have been analyzed.
Feature: It is now possible to re-load file system analysis data that was previously saved in XML format.
Feature: FolderSizes now has the ability to compare current file system analysis data with existing data (loaded from a previously saved XML scan file).
Feature: A new scan data explorer docking panel is available, providing a powerful new way to navigate (and act upon) the data that FolderSizes stores about the file system nodes it analyzes. With this new feature, it is now possible to view multiple file system root paths from the perspective of a single virtual root.
Feature: Excluded folders have been merged into the scan filtering user interface, and now are saved and loaded along with other scan filter criteria. Folder exclusions now also use an improved wildcard pattern matching engine, and can optionally be case sensitive.
Feature: A new report summary area has been introduced, providing detailed insight into any file system object(s) selected in the detail report. When multiple objects are selected, a summary of their totals and date ranges is displayed in the docking properties window.
Feature: The main analysis window now supports the entry of multiple paths, which will be scanned in succession. Users can enter multiple paths directly into the path input box (separating each of them with a pipe symbol) or use the multiple path manager window to browse for multiple paths individually. FolderSizes will detect when multiple paths are being analyzed, and will automatically bring the new scan data explorer docking pane into view in such cases, allowing the user to see (and navigate) the entire hierarchy of paths being analyzed.
Feature: Main window toolbar has been replaced with new ribbon-style tabbed command bar. This new command interface exposes richer controls, provides better organization (including smart resizing), and improves accessibility. All other window toolbars (e.g. search, file reports, etc.) have also been updated.
Feature: All window status bars have been re-designed with new, more informative and consistent indicator areas and intelligent use of available screen space.
Feature: The folder browser docking panel now supports keyboard navigation, and behaves more like Windows Explorer in various situations (selection state when closing an expanded node, etc.).
Feature: All file system node tooltips have been overhauled to show more information in an improved format, and are also now more pervasive and consistent.
Feature: A rich, new graphical view now appears when "My Computer" is selected within the Folder Browser panel. It also provides a simple mechanism for initiating the scan of multiple drives. Printing support has also been added.
Feature: Drive space data (as utilized by the Drive Space docking panel and "My Computer" views) is now collected on a separate thread, eliminating potential slowdowns in some circumstances and improving consistency amongst various views.
Feature: The main FolderSizes detail report view has been completely overhauled. Enhancements include:

Vastly improved printing and print previewing.
A powerful new file / folder properties area that shows data about current selection(s).
Improved application theme support.
A new column chooser mechanism, making detail view column management easier and more flexible.
Support for column alignment customization.
Improved column sizing for better use of available screen real estate.
Many other enhancements.

Feature: Bar graph drawing tolerances have been sharpened, with improved use of space overall. Horizontal label areas now resize themselves dynamically.
Feature: The main window bar, pie, and map graphs are now contained within independent docking panels for increased flexibility and customization support.
Feature: Error handling has been greatly improved across all file system analysis mechanisms, and error reporting has been enhanced significantly. There is now a common event log viewer with common access semantics and better usability (e.g. sorting, etc.).
Feature: On Windows Vista and later, new-style file and folder browser dialogs are used to select folder paths in various locations throughout the application.
Feature: The map graph has been improved substantially, and now better supports visualizing blocks of space consumed by files (not just folders). Performance has also been improved significantly.
Feature: The logic used to determine folder reparse point (symbolic link and junction) traversal safety has been greatly improved. Link targets are now fully resolved and compared against their parent folder path.
Feature: Scan filter system has been completely overhauled, and now provides the ability to specify multiple rules - each with their own match criteria. Scan filter rules can now also be specified for folders, with full include / exclude support and natural hierarchical result rendering.
Feature: The search facility also now uses rules-based criteria, similar to that used by scan filtering. The key difference is that search rules control what files and folders are returned as search results, whereas scan filtering controls what portions of the file system are analyzed.
Feature: Scan filtering can now be applied to searches for additional control over the scope of file system enumeration during the search process. Search scan filters are saved as part of the current search job (which can be written to / loaded from file). This feature also allows FolderSizes to provide seamless drill-down from many File Reports when the user double-clicks a detail item.
Feature: It is now possible to choose which columns are shown in every File Report detail view (by right-clicking the list header). This, in turn, affects the output of File Report data export operations (only visible columns will be exported).
Feature: The product "welcome wizard" has been overhauled to produce a richer, more useful introduction to FolderSizes.
Feature: There is now a switch (in graph section of options window) that causes all graphs to be rendered using allocated size (e.g. "size on disk").
Feature: A new command line switch, "/saveeventlog" can be used to save logged events to file. See help file for usage details. Note that if the "/date" command line option is used, the event log path will be appended with the current date and time.
Feature: The multiple path manager dialog window has been re-designed to be more usable, and enhanced with additional features such as the ability to save and load path sets to / from file.
Feature: Enhanced task scheduling to include support for multiple scan paths, as well as saving logged events to file.
Feature: Multiple enhancements to the FilterZip tool, including improvements in progress display window, retention of job state between uses, and a handful of bug fixes.
Feature: The default XSLT file that ships with FolderSizes has numerous improvements, including display of summary data and full disk space information. Overall formatting has also been improved.
Feature: All export file formats have been enhanced to improve consistency of data and formatting. Export performance has also been improved, and is supplemented by a progress indicator for all export file types.
Feature: Deletion of file and folder objects from within FolderSizes has been greatly enhanced, with smart consolidation of target objects and improved Windows shell services integration. FolderSizes also now does a much better job of reflecting such changes throughout its file system hierarchy database.
Feature: Product options window has been re-organized and improved (resizable, scrolling panes, theme support, etc.) and supplemented with additional options.
Feature: Overall theme support has been improved, with better consistency and appearance throughout the application.
Feature: FolderSizes no longer forces adminstrative elevation on Windows Vista and later when the executing user has a linked security token. On Windows Vista and later, a new "Run as Admin" ribbon bar command button will be enabled if the executing user is not already running elevated. As an added convenience, a special application shortcut also provides elevated execution capability (again, Windows Vista and later only).
Feature: Rename via right-click context menu is now supported in all file reports and search results.
Feature: Added "calculated" modified, accessed, and created date / time fields to the main detail view. These columns report the most recent date / time in the folder hierarchy, rather than the actual date / time reported by the Windows file system.
Feature: Added the ability to find the deepest folder nesting from within the scan data explorer tree.
Feature: When scanning multiple root nodes from within the main application window, separate threads are used to perform the analysis. This can result in greatly improved performance, particularly when the paths relate to distinct logical I/O channels (e.g. separate local drives, multiple network shares, etc.).
Feature: Added support for login and password to update checker proxy configuration. The authentication method will be determined automatically.
Feature: Added the ability to search one or more target folders using FolderSizes via the detail view right-click context menu.
Feature: Added the ability to load rules only from within search window. This feature will extract search rules from the target search job (.xml) file, but leave existing paths and scan filter settings alone.
Feature: Support for dragging and dropping of paths into FolderSizes has been greatly enhanced. Users can now drag and drop paths from Windows shell (and other apps) into the FolderSizes main window (anywhere), the file report generator window (anywhere), the search window (paths list box), or the multiple path manager window (anywhere). Support for multiple paths has also been added in all of these cases.
Bug fix: Now reporting aggregate search result size using "size on disk", rather than just flat file size.
Bug fix: Altered bar graph drawing routines to eliminate potential for minor visual artifacts under certain circumstances.
Bug fix: The folder browser panel no longer attempts to enumerate the contents of .zip archive files, which cause app startup delays in some circumstances.
Bug fix: Resolved issue with item selection in search / temp file detail listings when column sort changed.

Version 4.8.3.10 (Released February 22, 2010)

Feature: Options | Detail View now provides a switch that controls whether or not date-based detail columns will include times. Switch is on by default.
Feature: Added a counter to status bar of the main window to show the number of files scanned.
Feature: When a folder or drive shortcut (.lnk file) is dragged into the FolderSizes view window, the link will now be resolved (and the target folder will be analyzed).
Feature: Significant file system scanning performance improvements, particularly when scanning network volumes.
Bug fix: Scrollbars sizes did not always update immediately when adding columns to search / primary detail listings.
Bug fix: Leading and trailing spaces were not being properly trimmed from paths directly entered into the main window path box.
Bug fix: When using a preset date range within filter / search criteria, the times were not be adjusted to account for full days.
Bug fix: File dates report now normalizes min/max dates to encompass full days.
Bug fix: Resolved an issue with the "previous" path toolbar button not working in very specific circumstances.
Bug fix: In the file report generation progress display window, clicking the cancel button drop-down error and then clicking outside of the menu would still trigger cancellation.

Version 4.8.2.92 (Released December 28, 2009)]

Feature: The search facility now provides file and folder count columns. These columns are hidden by default - enable them by right-clicking the search listing header and selecting them from the resulting pop-up list.
Feature: Broadened the range of preset date ranges available in search / filtering facilities, and changed the phrasing to be more specific.
Feature: All report generation processes now show indeterminate task bar progress animation on Windows 7.
Feature: The main report, file report, and search windows now have a status bar pane that shows the number of folders being actively excluded.
Feature: All status bar panes now resize themselves as needed, rather than adhering to a fixed width.
Feature: Added the ability to cancel file report analysis and still show results (default is to cancel and discard results).
Feature: Enhanced and expanded existing visual themes. The "modern" theme now offers blue, black, silver, aqua, scenic, and white color sets (the "traditional" them remains unchanged).
Feature: Graph backgrounds now have the option (on by default) of matching the current visual application theme.
Bug fix: In specific circumstances, file report generation scheduled tasks would not start correctly.
Bug fix: If the Search Subfolders checkbox was disabled during a search, top-level folders would not be included in the search results.
Bug fix: When using the search facility, application-wide folder excusions were being incorrectly shown in the search results.
Bug fix: In some cases, it was possible to modify scan filter settings while report generation was in progress (should not be possible).
Bug fix: Resolved a cache logic defect that could cause report metrics to be miscalculated under certain specific circumstances.
Bug fix: Improved robustness when encountering certain rare file system corruption scenarios.
Other: Minor bug fixes and cosmetic improvements.

Version 4.8.1.74 (Released September 29, 2009)

Feature: Several improvements to the "modern" application theme.
Feature: Underlying ZIP archive file libraries have been updated for improved efficiency, compatiblity.
Bug fix: Resolved a problem with the excluded folder dialog allowing for the entry of paths already covered by existing entries.
Bug fix: Resolved a rare crash that could occur upon shutdown, related to the new background update checking implementation.
Other: Updated code signature with new security certificate.

Version 4.8.1.72 (Released July 7, 2009)

Feature: Added "Lost key" button to the product registration dialog to better assist users who have misplaced their product license details.
Feature: Added an automatic update checking mechanism to FolderSizes, which is enabled by default (and can be disabled via the options window). This feature will check for software updates in a background thread when FolderSizes starts, and will display a tray area notification when a newer version is available.
Feature: The map graph view is now drawn as the FolderSizes file system scan progresses. Previously, the map view did not render until scanning had completed entirely (in contrast to the other graph views, which rendered incrementally).
Feature: The main window pie graph view now offers two means by which users can limit the number of slices it shows. The first mode is by percentage of the parent folder, and is the default. The second (newly added) mode allows users to show only the "top N" largest pie slices.
Feature: Minor improvements to the product installer.
Bug fix: Personal edition licenses were incorrectly restricted from using the shell context menu (in some cases) to launch a new instance of FolderSizes.

Version 4.8.0.55 (Released June 5th, 2009)

Feature: Windows 7 is now fully supported.
Feature: FolderSizes now ships with a 64-bit version of its shell context menu for improved compatibility with 64-bit editions of Windows.
Feature: Main window visualizations (pie, bar, and treemap graph views) can now show allocated disk space (a "size on disk" computation that factors in cluster overhang, sparse file sizes, compressed file sizes, etc.) through the use of a new button in the graph pane toolbar.
Feature: Exporting reports in XML format is now vastly more scalable and memory efficient (the process now writes directly to disk, with minimal memory usage).
Feature: Main window XML exports now include disk space information (similar to the information available within the docking drive space panel).
Feature: A new "length" column has been added to the search window result list. This column is visible by default, and shows the length of the associated file or folder name. When the "count full path length" search option is engaged, the "length" column will reflect the full file system path lengths.
Feature: Search results and all file report detail views can now be exported as XML (previously, only main window reports could be exported in XML format).
Feature: Updated the integrated scheduler to provide support for XML export when scheduling file report or search tasks.
Feature: The file system scan error reporting window can now be resized.
Feature: If the "follow reparse points" option is engaged, FolderSizes will only follow links that point outside of the current scan directory. This prevents certain folders from being counted more than once during file system scans, and will also prevent recursion loops.
Feature: Added an "exclude folders from search results" switch to the FolderSizes search facility. This feature is switched on automatically when drilling down into certain file reports (which launches a search), improving consistency between these two systems.
Feature: Added "allocated" detail view column to the following file reports: file type, attribute, size, name, duplicates, and date.
Feature: Added the ability to search (or filter) by allocated file system object size (e.g. "size on disk").
Feature: Minor adjustments to allocated disk space calculations for compressed files of small size.
Feature: Improvements to the bar graph drawing routines to sharpen the appearance of the bars.
Feature: The options controlling the number of entries shown in the largest and oldest file reports has been moved to their respective report windows (and out of the general file report options window) for more intuitive access and improved consistency.
Feature: The "largest" and "file sizes" reports can now optionally perform their comparisons by allocated file size (e.g. "size on disk").
Feature: Sorting speed for the following file report detail views has been greatly improved: oldest, largest, duplicate, and file type.
Bug fix: Keyboard shortcuts within the search and file report generation windows would stop working under certain circumstances.
Bug fix: Resolved an issue with bar graph widths not computing correctly in rare circumstances.
Bug fix: The banding graph of the largest files report would produce inaccurate results under very specific circumstances.
Bug fix: The default number of entries in the largest and oldest file reports were inconsistent between the option display and the report generation process.

Version 4.7.0.37 (Released September 10th, 2008)

Bug fix: Resolved a floating point runtime error that could occur in certain environments.

Version 4.7.0.36 (Released August 19th, 2008)

Feature: Added a new "folder map" graph view, based upon the TreeMap data visualization method. This new view provides an alternative to the existing bar and pie graph views, showing the complete subfolder hierarchy at a glance.
Feature: Made the new folder map graph type available for inclusion within HTML exports (in addition to the existing pie and bar graph types). It can be accessed during HTML report exports via use of the /graphtype:"map" command parameter.
Feature: Improved error handling during generation of XML export file data. The default XSLT file has also been improved to better display XML data generation errors when they occur.
Feature: Added file owner to graph (bar, pie, and map views) tooltips. Also improved tooltip apperance timing when moving from one graph entry to another.
Feature: Added a new panel to the options window for the folder map. The map start and end colors can now be configured, as well as a few additional options.
Feature: Added support for a new "Personal Edition" license type, designed specifically for home users. See help file for description of this new license type, along with limitations.
Feature: Right-click context menu can now add multiple selected folders to the folder exclusion listing (previously, only one at a time was possible).
Feature: The folder browser panel shell tree now does a better job of staying in sync with the current file system analysis path, even in cases where that path are unknown to the folder browser. Unusual conditions (such as drilling into file system folders not visible to the shell, etc.) are now handled gracefully.
Feature: Substantial improvements were made to XML export capabilities, including significant performance enhancements as well as overall output size reduction. Please note that the structure of the XML output has changed, so if you rely on external applications to analyze this data then you'll need to revisit those. Similarly, if you've customized the XSLT file that ships with FolderSizes, those customizations will need to be revised.
Bug fix: The pie graph view now honors the label font selection made in the graph options panel.
Bug fix: Fixed a rare crash that could occur under very specific report rendering conditions.
Bug fix: The Oldest Files detail report view date column would be blank when using "date accessed" as the reference file system time stamp.
Bug fix: XML file export "depth" column was providing incorrect value.
Bug fix: The banding graph of the largest files report was not being updated when file objects were deleted from the detail listing.
Bug fix: Minor corrections to internal cache database logic.

Version 4.6.0.44 (Released June 30th, 2008)

Bug fix: Resolved a problem with command line execution of FolderSizes with a very specific form of parameterization.
Feature: Other minor cosmetic enhancements (new file open / save dialog support on Vista, etc.).

Version 4.6.0.42 (Released June 5th, 2008)

Various minor (mostly cosmetic) bug fixes.

Version 4.6.0.40 (Released June 1st, 2008)

Bug fix: Resolved a problem where paths greater than 260 characters would cause a runtime error in some scenarios.
Bug fix: The "research file extension" function of the FolderSizes file / folder context menu was not properly enabled in some circumstances.
Bug fix: The search facility would fail when attempting to show full folder paths exceeding 260 characters in length.
Bug fix: Resolved a problem with the integrated Windows shell context menu not displaying all items properly in certain circumstances.
Feature: Improved handling of very long paths in several ways, including improved drill-down into long paths from the Folder Browser, handling of long paths in the main window Path entry field, and more.

Version 4.6.0.37 (Released May 26th, 2008)

Feature: FolderSizes now provides an integrated task scheduling facility. This tool makes it much easier to schedule file system analysis operations through the FolderSizes command line interface by wrapping it with an intuitive graphical user interface and interoperating directly with the Windows scheduling system.
Feature: Added several new switches to the File Reports section of the options window. These switches allow users to disable file owner lookup operations for the largest, oldest, and duplicate file reports individually. Doing so can increase the speed of file report generation operations considerably, especially when scanning remote (network) file systems.
Feature: Improved the speed at which File Reports are shown upon completion of scanning operations.
Feature: Improved memory utilization for a variety of reporting scenarios. This is particularly noticeable when performing larger-scale File Report analyses with the duplicate file report enabled. In many such cases, memory use has been reduced by roughly 60%.
Feature: Introduced a file owner lookup caching mechanism that can help speed the generation of certain types of reports (especially on subsequent reporting runs within the same session). By default, file ownership lookups will be cached for remote (network) paths only, with a maximum memory allocation of 2048 Kb. These values, as well as the enabling / disabling of the cache entirely, can be changed in the Scanning section of the options window.
Feature: Vastly increased the scalability of Duplicate File report export operations; export file generation now uses much less system memory.
Feature: Allocated file / folder size computations now better handle sparse files (which are often generated by HSM and archiving software solutions).
Feature: Added "allocated" file size columns to largest, oldest, and temporary report detail views.
Feature: The "largest", "oldest", and "temporary" file reports - as well as the search facility result listing - now honor the folder and file attribute color defined in the "detail view" section of the options window.
Feature: Switching visual application themes (via the View menu) no longer requires a re-start. The option to use a "traditional" visual theme (as opposed to the default "modern" theme) is now also presented in the welcome wizard.
Feature: Added a "filename only" match option to the duplicate file report generation window. The duplicate file report master / detail view was also modified to accommodate this change (e.g. the file size column was moved from the master view to the detail view, since duplicates can now differ in size when using "filename only" matching mode).
Feature: The duplicate report HTML output format was improved significantly; it's now much more readable, and makes better use of available space. It also produces smaller HTML files that open faster within a web browser.
Feature: Numerous other user interface enhancements, including improved (themed) button appearance, etc.
Feature: The license reminder dialog window will no longer appear when launching FolderSizes via the command line during the default evaluation period (unless the trial period has expired). This allows for a more thorough evaluation of command line / scheduling features prior to licensing FolderSizes.
Feature: FolderSizes now maintains a more consistent and accurate internal analysis data cache. Deletion of files and folders from within the main detail view no longer invalidates the entire cache (thereby forcing a re-scan of previously viewed file system nodes). Further, such removals are now immediately reflected in parent folders during navigation operations.
Feature: The search window status bar now also shows cumulative search result file size (in addition to existing file count), and has a new (more performant) update mechanism.
Feature: The Filter Options tab of the scan filter window has been updated to better reflect the various filter criteria exposed through the remaining tabs.
Bug fix: Tooltips were not showing properly for all bar graph items when the view was scrolled.
Bug fix: The "space consumed" indicator of the duplicate file report was not being updated when duplicate files were deleted.
Bug fix: Resolved a minor visual glitch that would appear when un-pinning the folder browser window.
Bug fix: The right-click context menu for the Temporary Files Report was not working correctly. This has been resolved.
Bug fix: In the search results list, it was not possible to right-click a file and "Explore Folder". This has been fixed.
Bug fix: It was not possible to navigate amongst FolderSizes search results by typing the first letters of a file name on the keyboard. This has been resolved.
Bug fix: Resolved a numeric overrun that occurred when drilling down into the default "4GB+" file size report detail view entry.

Version 4.5.1.1 (Released April 9th, 2008)

Bug fix: Resolved a cosmetic issue with the folder browser and disk space docking panel titles.

Version 4.5.1.0 (Released March 15th, 2008)

Feature: Added a new view menu switch that allows users to change the "visual theme" of the application to a more traditional (more Windows XP like) form.
Feature: Added a new "exclusion mode" toggle to the date criteria section of the search window. This makes it easy to execute queries such as "find all files NOT modified within the last 30 days", etc.
Feature: Added new "depth" column to the main window detail listing. This new column shows the specific depth of the file system object it references. This is particularly useful in combination with the "View | Subfolder Display Depth" options, and be used to isolate deeply nested paths. This new column is hidden by default; right-click on any detail view column header to toggle it on.
Bug fix: If the graph view panel is "collapsed" prior to exiting FolderSizes, this state is now restored the next time the program is started.
Bug fix: Resolved a problem with the banding graph on the largest files report window not showing very large files correctly.
Bug fix: Fixed a problem where wildcard filename match expressions using spaces were not functioning correctly.
Bug fix: The FolderSizes v4.5.0.1 was not digitally signed; this has been corrected.
Various minor fixes, help file clarifications, etc.

Version 4.5.0.1 (Released February 3rd, 2008)

Bug fix: Resolved regression discovered in the 4.5.0.0 production release. Largest and oldest file classification reports would not return correct results in some circumstances.

Version 4.5.0.0 (Released February 1st, 2008)

Feature: FolderSizes is now Unicode enabled. Folders and files containing Unicode characters can now be scanned / displayed without error, and will also be carried over properly into report exports, etc.
Feature: It is now possible to execute FolderSizes search jobs from the command line, including full support for report exporting in multiple formats. Please see the "Using FolderSizes" section of the help file for details.
Feature: File system object names and paths are now sorted with an improved algorithm that yields more intuitive sort results (especially when file system object paths contain numeric components). Sorting has also benefited from several performance enhancements as well as improved Unicode character consideration.
Feature: Added "last modified" column to "temporary" and "largest" file report detail views.
Feature: The search facility has greatly improved support for folders, which now carry their own size information. Folder sizes are now displayed on-screen in the search results, and are also used in search filter criteria comparisons. A "directory" switch has been added to the attribute section of the search critieria, allowing for easy inclusion or exclusion of folders in search results. Sorting has also been improved to isolate folders from files.
Feature: Considerable performance enhancements within several of the file report detail views (particularly noticeable when working with network paths).
Feature: Added "folder count" and "elapsed time" statistics to the file report scanning window display.
Feature: All "browse for folder" dialogs now remember previous path selections in a more consistent manner (for performance reasons, UNC paths do not apply).
Feature: Numerous user interface improvements, including streamlined status bars, improved bar graph appearance, and more.
Feature: The file extension browser tool is now available from the tools menu of the main application window. This tool also now provides a resizable window and makes better use of available screen real estate.
Feature: The main window pie graph view now provides robust tooltips when hovering over pie slices (similar to what the bar graph view already provides). Toolbar tooltips throughout the application have also been made more useful.
Feature: Data export files are now all written in UTF-8 format; including files in XML, HTML, CSV, and TXT formats. There is also a new checkbox in the Reports::Export section of the settings window that allows you to toggle on/off the inclusion of a BOM (byte order marker) for UTF-8 encoded text files (e.g. CSV and TXT formats). Please see the help file for usage details.
Feature: Extended the search window status bar to separate a "files found" counter into its own pane.
Feature: The File Name Masks section of the filtering and search facilities now provide more granular exclusionary capabilities when operating in wildcard mode. Individual mask segments can now be preceded by a tilde ("~") to make them exclusionary (see help for details). Important: This capability replaces the "exclude (rather than include)" switch previously available from the File Name Masks section of the filtering and search windows. Please be sure to update any existing scan filtering / search job definitions that use this switch.
Feature: Paths within the search facility can now be edited by double-clicking on them. These paths also now have tooltips.
Feature: Now if you right-click within the drive space docking panel list control header, the "save to file" option is available. You can use this to output the contents of the drive space panel list to file in HTML, CSV, or TXT format.
Feature: In the attribute matching area of the search and filtering windows, a new switch allows for control over the matching mode employed. Setting this to "match all" requires that a file match any selected attribute before being included in any results. The "match any" mode operates consistently with previous FolderSizes releases, and is the default.
Bug fix: Resolved a crash within the file reporting window that could occur when a scan was cancelled and previous results were being displayed.
Bug fix: Resolved a problem in which the "parent folder" column of the FolderSizes search results detail listing was not sorting in a manner consistent with normal user expectations.
Bug fix: The "exclude pie graph labels" option (located in the "graph pane" section of the options window) was not working properly. This has been fixed.
Bug fix: Fixed a problem in which certain graph toolbar options were not properly enabled when scanning a folder consisting entirely of files (and no sub-folders).
Bug fix: Resolved a cosmetic bug that caused certain tooltips to always be shown, even when they were disabled globally from within the options window.
Note: Support for Windows 98 and ME has been dropped.

Version 4.2.0.0 (Released December 4th, 2007)

Feature: File exports now provide more intuitive default names for exported files.
Feature: By default, HTML report exports will now have CSS style settings merged directly into their page headers. This functionality can be controlled through a switch in the Export section of the options window. When the switch is disabled, FolderSizes will copy a CSS file separately and link to it from the HTML report page. Either way, users are still free to alter the style settings contained within "template/style.css" (located below the FolderSizes installation root folder) to alter the look and feel of HTML exports.
Feature: Users can now control (via a switch in the Exports section of the options window) whether or not the FolderSizes XSLT file is utilized by XML exports. When used, the XSLT file is now copied from the "xslt" subfolder of the FolderSizes installation root to the same path as the XML report file. These improvements provide more flexibility in how / where XML reports can be distributed.
Feature: The main window "Up" navigation function (which navigates to the parent of the current folder path) now supports UNC paths.
Bug fix: Folder exclusion paths will fail to match properly if they contained a trailing backslash. Such backslashes are now automatically removed to help ensure expected behavior.
Bug fix: Folder exclusions were not always being properly applied to folder data that had been cached in previous scanning operations.
Bug fix: Options window navigation tree was not being drawn correctly on some operating systems( v4.1.1.1 regression).
Bug fix: Resolved a screen re-painting problem that could occur within the file reporter window during certain control validation operations.
Several other minor enhancements and bug fixes

Version 4.1.1.1 (Released November 20th, 2007)

Bug fix: Resovled a problem with wildcard pattern matching not working as expected under some conditions.

Version 4.1.1.0 (Released October 20th, 2007)

Feature: When FolderSizes (a 32-bit application) is run on a 64-bit computer (with a 64-bit Windows operating system installed), it will now disable WOW64 file system redirection during the file system scanning process. There is a new switch within the scanning area of the options window that allows you to turn this feature on or off (it is on by default).
Bug fix: Resolved a cosmetic defect that occurred when deleting items from the search results window. In some cases, the detail list control would not be updated correctly.
Bug fix: Resolved a problem with the backspace not being processed correctly within the path entry field in the main application window.

Version 4.1.0.0 (Released July 23rd, 2007)

Feature: Integrated a new File Extension Researcher tool, allowing users to gather additional information on file extensions that they encounter across various file systems (including potential application associations). The ability to research file types by extention has been integrated (through context menus, buttons, etc.) throughout the various FolderSizes detail views.
Feature: Implemented a new File Extension Browser window, designed to supplement (and currently accessible from within) the File Extension Researcher tool described above. This window allows users to browse a database of known file extensions in an intuitive fashion (e.g. extensions are grouped by their starting letter, numbers, and symbols).
Feature: The results detail listing within the search window is now fully customizable. Right-click the detail list column header and select the field names you wish to view (de-select the ones you wish to hide).
Feature: Added two new columns to the search window detail list that show the date the file was created, and the date it was last accessed. Note that these columns are hidden by default (right-click the detail list header to customize columns shown).
Feature: File owner column added to "Largest Files" and "Oldest Files" file reports.
Feature: Added file creation date column to main exploration detail view. This new column is hidden by default (to make it visible, right-click the detail view column header and select it from the popup menu).
Feature: Within the search and filtering windows, the date range specification area now offers a handful of convenient presents (e.g. "within last day", "within last week", "within last month", and "within last year"). You can, of course, still elect to specify a custom date range if desired.
Bug fix: Resolved a problem with the date range portion of the file search facility effectively preventing the "to" and "from" dates from being the same day.
Various minor improvements and corrections.

Version 4.0.0.1 (Released May 4th, 2007)

Bug fix: Resolved problem with spurious floppy drive seeks during certain user interface refresh operations.

Version 4.0.0.0 (Released April 18th, 2007)

Feature: File Reports now support the use of multiple file system scan paths. A new "multiple paths" button has been added to the main File Reports window for this purpose. Multiple paths are also supported during command line operations (which have been greatly expanded - see below) and file report drill-down operations (which now carry multiple paths into the FolderSizes Search window).
Feature: Numerous improvements to the FolderSizes command line interface, including support for exporting the contents of File Reports, use of the "/exit" switch in combination with File Reports, application of scan filtering criteria, generation and export of multiple File Reports within a single command, a simplified syntax ("/xml", "/html", "/csv", and "/txt" switches were all replaced with a single "/export" switch), and more. See the "Command Line Support" section of the product help file for more information.
Feature: The FolderSizes search and scan filtering facilities have been extended to support a new "file name length" criteria. This makes it possible to quickly identify (and filter against) file system objects by the length of their names. It is possible to count the file name alone (the default), or the fully qualified path.
Feature: The File Names report (part of the File Reports window) now supports drill-down. Double click a report entry in the detail view to automatically launch a search for file name lengths with the selected range.
Feature: Added a new "fast shell icon collection mode" switch to the Detail View section of the options window. This switch forces FolderSizes to deduce file system object icons from the type of file (rather than opening the file). This switch can provide a considerable performance boost when exploring remote file systems, and it is engaged by default.
Feature: Added a switch to the general settings (tools | options | settings) that allows the shell context menu to be enabled or disabled.
Feature: Numerous improvements to keyboard / shortcut handling. Existing shortcuts have been simplified and clarified, and a couple (such as support for Ctrl+A to select all entries in file system object lists) new ones added.
Feature: Added a visual bar graph indicator to all "% of Parent" columns in various detail views throughout the application.
Feature: Added the ability to configure Windows System Restore via a new item in the Tools menu. Windows System Restore often has considerable impact on local disk space.
Feature: Added a new "attributes" column to the main exploration view list (hidden by default; right-click the column header to reveal it) and to the search results window (represented in XML data exports called "AttribString").
Feature: Added a new "avg. file size" column to the main exploration view list (hidden by default). Included in the XML export in both numeric and string formats.
Feature: Added file owner column to duplicate file report detail view (as well as data exports).
Feature: FolderSizes now displays a "landing page" when it starts up, designed to assist users in beginning a file system scan.
Feature: Numerous changes to better support the Windows Vista operating system. For example, default per-user settings files are now stored in the user's "application data" folder, and not in the product installation folder, various registry settings have been re-located, etc.
Feature: Use of the "/date" command line parameter now appends the current time (along with the date) to the export filename in "HHMMSS" format.
Feature: When exporting any FolderSizes detail report (including search results, file reports, etc.) to CSV format, a new "Size in Bytes" column is now added automatically. This greatly facilitates analysis of export data within third-party applications such as MS Excel.
Feature: Improved the overall robustness of the file system scanning engine, including enhancements to reparse point (e.g. junction, symbolic link) processing and error handling routines.
Feature: Numerous minor improvements to the FilterZip file compression tool, including improved file system scan error handling and user interface consistency changes.
Feature: The "My Computer" view (triggered when "My Computer" is selected within the Folder Browser panel) can now be exported in CSV format, and is now fully sortable (by any column).
Feature: The bar graph view within the main application window has been improved to include file system icons (next to graph labels) for easier visual identification. The bars are also now drawn with an attractive gradient effect.
Feature: When selecting file system objects in the main window detail view, the number of objects and their aggregate size now appear within the first pane of the status bar. This feature is also provided in the FolderSizes search window.
Feature: Scan filtering criteria can now be loaded from (or saved to) file, and can be applied during command line operations (see documentation for details). The filter criteria can also now be reset to their default values.
Bug fix: Resolved a problem with internal file filter matching algorithms not correctly comparing file system object attributes in some cases.
Bug fix: Resolved a problem with automatically opening HTML reports exported from certain File Report windows.
Bug fix: Resolved an issue with the toolbar Refresh button not always working consistently when dealing with UNC paths.
Bug fix: Resolved a rare path length related race condition in the Oldest Files report display processor.
Bug fix: Resolved a rare bug that would cause Oldest / Largest file report heap sizes not to initialize correctly between scans.
Bug fix: Resolved an issue with the drive space panel graph view not always auto-refreshing.
Many miscellaneous cosmetic and usability enhancements, documentation updates, and minor bug fixes.

Version 3.6.1.1 (Released December 2nd, 2006)

Bug fix: Resolved a dynamic cluster size discovery defect introduced in v3.6.1.0.

Version 3.6.1.0 (Released November 30th, 2006)

Feature: Added the ability to count full path lengths in the File Names detail report. This makes it easier to determine when very long file paths might be interfering with disk access operations on your network, for example.
Feature: Cluster size recognition for local and remote file systems is now much improved. An option has been added to the "general" section of the settings window allowing for the specification of a default cluster size, to be used when the cluster size of a target file system path cannot be automatically deduced.
Feature: Added the ability to manage the file name mask presets available during search and scan filtering operations. Users now have the ability to edit any pre-defined filename search mask (e.g. "images", "movies", etc.) and may now also define up to two custom masks.
Feature: The range-based File Reports (e.g. File Sizes, File Names, and File Dates reports) now honor overlapping range definitions.
Feature: Improved the scalability of HTML based report exports initiated from the main FolderSizes window (via File | Export).
Bug fix: Resolved issue with commas being stripped from certain fields during CSV export.
Bug fix: Resolved an issue with empty files assuming the consumption of a cluster on disk.
Assortment of minor bug fixes.

Version 3.6.0.1 (Release March 15th, 2006)

Minor bug fixes to new long folder and file name support.

Version 3.6.0.0 (Released March 3rd, 2006)

Feature: Better overall support for very long folder & file names on the Windows 2000/XP/Server 2003 platforms.
Feature: Search facility now returns folder objects (in addition to files). Note that a filename mask of "*.*" will cause the search results to contain only files (with extensions), whereas a filename mask of "*" will match both files and folders.
Feature: Added new right-click context menu to Drive Space Panel detail view. The detail view can now be printed and copied to the Windows clipboard.
Feature: The contents of the report that appears when "My Computer" is selected in the folder browser pane can now be printed.
Feature: The folder exclusions facility is now more flexible. Exclusions can now be selectively applied to normal scan results, file reports, and / or search results. By default, folder exclusions apply to all three areas.
Feature: Deleting objects larger than the recycle bin can accommodate will now prompt the user for confirmation.
Feature: Better overall usability in the Folder Exclusions window - previously browsed paths are now remembered, better path deletion behavior, and more.
Bug fix: Some settings in the File Name Masks tab of the scan / filter definition windows were not being saved (or therefore subsequently re-loaded) correctly.

Version 3.5.0.1 (Released September 4th, 2005)

Bug fix: The "/exit" command line parameter was broken in the v3.5.0.0 release, and has been repaired.
Feature: Minor usability tweaks to the search facility. Search results list now processes the delete key, browsing for new search paths now remembers last path, and more.

Version 3.5.0.0 (Released August 20th, 2005)

Feature: FolderSizes now ships with an XSLT file that formats exported XML files for display in a browser that supports XSLT processing (e.g. Internet Explorer v5.5, Firefox v1.0, etc.). Keep in mind that large XML files may take a while to load and display in the browser.
Feature: Added keyboard shortcuts to the FolderSizes Search and File Reporting facilities. Hovering over a toolbar button within one of these windows will reveal the button's shortcut key combination.
Feature: Added search definition reset button to FolderSizes Search window. This function resets all search criteria, with the exception of search paths, to their defaults.
Feature: Added powerful regular expression support to scan filtering (file name masks) and search windows.
Feature: Added a "case sensitive" matching option to the file name masks section of the search and scan filtering facilities. Works with both wildcard patterns and regular expressions.
Feature: The "Duplicate Files" file report can now be exported as comma or tab separated values (in addition to the HTML export support that already existed).
Feature: Revised the product help file and transitioned it to HTML Help format, which provides better overall usability.
Bug fix: The properties menu option within the FolderSizes context (right-click) menu was broken, and has been fixed.
Bug fix: Resolved directional bug in temp file report sorting.
Bug fix: Resolved detail view sorting issues with the range-oriented file reports (file sizes, file names, and file dates).
Bug fix: Resolved a case where FolderSizes could crash during shutdown if a file system scan was in progress.
Bug fix: The pie graph view would not re-draw correctly after a file report was generated.
Numerous minor improvements.

Version 3.4.0.0 (Released July 10th, 2005)

Feature: Added ability to customize primary application command bars.
Feature: Implemented more dynamic dockable (and now also pinnable) panels for the "folder browser" and "drive space" windows.
Feature: Added an "Explore From Folder" option to list view context menu. Works similarly to "Cmd Prompt From Folder" in that it will operate against the containing folder of files (or against folder paths directly).
Feature: Added a new option to list view context menu which copies paths to clipboard without a summary header.
Feature: Made several improvements to the formatting of XML export output.
Bug fix: Resolved a problem with certain menu items not drawing correctly in Windows Media Center Edition.
Bug fix: Resolved a problem with FolderSizes crashing when using the "/exit" command line argument under certain circumstances.
Bug fix: Resolved a problem with the main list view window not refreshing when deleting file system objects from UNC-based paths.
Change: Removed Add/Remove programs from the primary application toolbar. This capability is still available from the Tools menu.
Numerous other minor enhancements and fixes.

Version 3.3.0.0 (Released April 7th, 2005)

Feature: Modified the context menu (right-click) "cmd prompt here" function so that it will process file paths as well as folder paths. When it encounters a file path, it will simply open the containing folder.
Feature: Added a new "/noshowreport" command-line switch, which can suppress the showing of HTML report exports in the default web browser (even if this option is enabled within the options window). Usage example:
Example: foldersizes.exe /path:"d:\temp" /html:"d:\temp\myreport.html" /noshowreport /exit
Feature: Added additional pie graph view controls, accessible via the "View->Graph Display Options" submenu. Users can now flatten the pie graph (e.g. remove the 3D effect) or force it to remain circular. It also now possible to zoom the pie graph in and out (using the same submenu commands, or via Ctrl+Alt+Z and Ctrl+Alt+U).
Feature: File report export operations now use direct-to-file buffering, which allows FolderSizes to export much larger file reports without taxing memory resources.
Feature: Added a new "compare filenames only" to the filename masking section of the filter / search windows. Previously, the entire path would be compared against the filename mask(s), which was sometimes counter-intuitive. This new option is engaged by default.
Feature: When using the right-click context menu to copy paths to the clipboard, file count and total size information is now pre-pended to the clipboard text. This currently applies to the main report list view, search results, and the duplicate file report.
Bug fix: Resolved a problem that would prevent file icons from appearing in certain situations on Windows XP Media Center edition.
Bug fix: Resolved a crash that would occur if "My Computer" was selected in the folder explorer pane while the options window was exited.

Version 3.2.0.0 (Released March 3rd, 2005)

Feature: Selecting "My Computer" from the folder browser window pane now causes FolderSizes to show disk usage statistics for local, network, and other drive types.
Feature: Added "total space consumed" indicator to the duplicate file report, which shows the total amount of disk space consumed by all duplicate files found during scanning operations. This value is also now included in the HTML export for this report.
Feature: Increased the maximum number of entries allowed in the "oldest files" and "largest files" reports from 9,999 to 9,999,999. Changed default value from "50" to "100".
Feature: Added the ability to save file system scanning (e.g. folder enumeration) error reports to disk.
Feature: Search window will now report any errors encountered during file system scanning, just as the file report generation and main application windows do currently.
Bug fix: Resolved a minor issue with the disk space docking panel graph tab not updating in a timely manner in some circumstances. Also added manual refresh capability to graph tab via right-click context menu.
A handful of other minor enhancements and cosmetic bug fixes.

Version 3.1.0.2 (Released Jan. 1st, 2005)

Bug fix: Restored the toolbar tooltips that were broken with the v3.1 release.

Version 3.1.0.1 (Released Dec. 28th, 2004)

Bug fix: resolved a v3.0 release defect that broke compatibility with NT4.

Version 3.1.0.0 (Released Dec. 23rd, 2004)

Feature: The view setting "Show Files" (previously named "Show Files in Detail View") will now display files in the graph views. Previously, both files and folders appeared in the detail view but only folders appeared in the graph views. This change provides a better overall spatial perspective, particularly when scanning a file system path that contains only files (and no sub-folders).
Feature: Modified the detail folder / file view sort algorithm so that it better emulates that used by Windows Explorer. The changes are somewhat subtle, and affect the placement of folders versus files when sorting by file system object name.
Feature: Files displayed in the main bar/pie graph views are now shown in gray to differentiate them from folders (which are shown in black).
Feature: Numerous minor usability and cosmetic enhancements.
Bug fix: Resolved an issue with the sort icons in the search window list control not displaying correctly.

Version 3.0.0.2 (Released Nov. 8th, 2004)

Feature: Added new "scan filtering" capability. Now, users can limit file system scan results using a number of criteria, including file name masks (multiple masks supported), date ranges (using modified, created, or last accessed time stamps), file sizes, attributes, and file owners (with wildcard support). Further, scan filtering can be applied to normal scans (the ones displayed in the main user interface) or File Reports (or both).
Feature: Added a new "File Sizes" file report. This report allows you to define file size categories into which files are sorted during scanning operations. The File Sizes report is supplemented by a bar graph view, and is accessible via the command line as well as the FolderSizes shell context menu extension.
Feature: Added a new "File Names" file report, which sorts files into defined filename length categories. This is very useful for understanding file distribution by filename length. The File Names report is supplemented by a bar graph view, and is accessible via the command line as well as the FolderSizes shell context menu extension.
Feature: Added a new "File Dates" file report, providing users with the ability to define date categories into which files are sorted during scanning operations. The File Dates report is supplemented by a bar graph view, and is accessible via the command line as well as the FolderSizes shell context menu extension.
Feature: Added a powerful new search facility to FolderSizes. This allows users to find files in multiple folders at once, using multiple file masks (e.g. wildcard patterns) and a variety of other criteria (file size and date ranges, etc.). Search results can be printed or exported in several formats (HTML, CSV, etc.). Search jobs can also be saved and then loaded later for re-use.
Feature: Many file report detail views now support search drill-down. Double-clicking a "file attributes" detail report item, for example, will automatically find and display all related files. This also works for "file types", "file sizes", "file dates", "file owners", etc. Drill-down searches adapt themselves automatically when scan filtering is enabled (see above for more about scan filtering).
Feature: New report HTML export option allows the user to omit the folder listing. This is useful in cases where you want an HTML export to contain only drive information and a graph, for example.
Feature: Added a status bar to the File Report generation window with several useful indicators.
Feature: Added an option to exclude labels from the pie graph view.
Feature: Added file system type (e.g. NTFS, FAT32, etc.) column to the drive space docking panel list view.
Feature: Added a new command-line switch for setting the subfolder display depth (for the current scan only). The parameter is "subdisplaydepth". Here's a usage example:
Example: foldersizes.exe /path:"d:" /subdisplaydepth:"3" /exit
Feature: Numerous minor improvements in overall usability, appearance, and performance.
Feature: Added a new "Command Prompt Here" function to the "tools" menu. This opens a command window directly to the folder currently displayed in the FolderSizes path drop-down box.
Feature: Added an option for limiting the number of bars included in bar graph exports. By default, the limiting option is enaged and set to 100, but it can be altered (or disabled) within the options window. The setting applies when saving a bar graph directly to file, or when saving it as part of an HTML report.
Feature: File type pie graph display is now sorted by file size descending. Also now provides a toggle for displaying or hiding the pie graph labels.
Bug fix: Resolved a defect that caused multiple-selections of folders and/or files in certain lists to fail. This would occur when the file system objects in question did not share a common parent folder, and is a result of a limitation in the Windows shell. The fix is a new context menu wrapper that provides its own, more robust, deletion capability (among other things).
Bug fix: Resolved a problem where excluding the currently selected folder from a scan would cause an exception upon refresh.
Change: The "last accessed" column in the main, upper-right detail list view is now hidden by default. You can, of course, always right-click the column headers and re-display this column.

Version 2.7.0.1 (Released August 18th, 2004)

Feature: The drive space panel now has a new graph format. Rather than requiring the user to manually switch between drives using a drop-down box (resulting in the display of a pie graph), FolderSizes now shows all drives at once using a stacked horizontal bar graph. This greatly improves the "at-a-glance" usefulness of the drive space panel graph.
Feature: Right-clicking the drive space panel graph now provides the ability to copy the graph to the cipboard, save it to file in a number of different image formats, or print it.
Feature: Bottom graph axis labels now use more intelligent, user-friendly size displays (e.g. adaptive sizing versus bytes only).
Bug fix: Repaired an issue with deleting a folder from the folder browser pane when the contents of that folder were on-screen. This defect was introduced in a very recent minor revision, and is now corrected.
Bug fix: Resolved a minor bug that caused column spacing in the main detail view to be save improperly when certain columns were hidden.
Other minor improvements and bug fixes.

Version 2.6.0.2 (Released July 26th, 2004)

Feature: The File Report Generator interface has been re-designed. The primary goal of the re-design was to allow for better navigation of the growing list of file reports (there are now ten of them!). The tabbed interface has been replaced by a treeview style navigation system. The enabling and disabling of specific File Reports has been moved to the main options window.
Feature: Added a pie graph view to the File Owners report, providing better visualization of disk space resources by file owner. Supports printing, exporting to multiple formats, etc. Updated the shell context menu, help file, and command line support systems to reflect new report availability.
Feature: Added a detail view for the file attribute report (previously only a graph was available). Supports printing, exporting to multiple formats, etc. Updated the shell context menu, help file, and command line support systems to reflect new report availability.
Feature: Updated product documentation to reflect new and improved features and layout changes; also made general content improvements.
Feature: All File Report detail views now retain their current sort column and order between program instantiations. Further, all detail lists in the entire program now show the sort order immediately (as soon as they are shown), rather than after a scan completes.
Feature: Added Explorer-like folder and file renaming capability to main detail view.
Feature(s): Numerous minor performance improvements, tweaks, and functional enhancements.
Bug fix: Resolved minor issue with product showing two expiration warnings when the end of the evaluation period was near.
Bug fix: Resolved a very rare (never reported) issue with FolderSizes crashing on the Windows 9x platform when the shell context menu was right-clicked twice from within the FolderSizes user interface.
Bug fix: Resolved a fairly rare right-click bug fix that occurred on some non-English versions of Windows XP.

Version 2.5.0.3 (Released July 10th, 2004)

Feature: Added a "File Owners" file report, which provides a breakdown of file usage (in the scan path) by owner / group. As with the other file reports, "File Owners" can be accessed via the FolderSizes shell context menu extension, via command line, etc. The contents of the report can also be exported or printed.
Feature: Added support for HTTP proxy traversal to the FolderSizes update checker. See the options window (under general->update checker) for specific configuration options.
Feature: Updated the product documentation to include all of the more recently added command-line options, newer option settings, etc.
Feature: Added the ability to hide / show columns in the detail list view (upper right). Simply right-click the detail list view column header to see a column selection pop-up menu. Note that exports of detail view information will use whatever columns are currently visible (hidden columns will not be exported).
Feature: The temporary file reporting system has undergone a signficant overhaul, and now uses wildcard-oriented match patterns. This allows for much more accurate temp file matching overall without losing any speed. Note: when upgrading FolderSizes, any custom temp file match patterns will be overwritten with the new default wildard patterns.
Feature: Numerous additions the online product help file.
Feature: File or folder owners are now displayed with their containing domain, if applicable. Note that some user account are pre-defined by the operating system; in these cases, the domain name will be "BUILTIN".
Bug fix: Resolved bug in "size on disk" calculations when NTFS cluster size was not 4k (which it is by default).
Change: By default, the detail list view is now sorted by size (in descending order). Custom sort order and direction will, of course, still be retained and honored for existing installations.

Version 2.4.0.3 (Released Mid-May, '04)

Feature: Added an "Allocated" column to the detail list view that shows the actual "space on disk" consumed by a given file or folder. Also added the new "allocated" value to the report exports (including XML, which has a literal value in bytes and a string representation). Note that the "allocated" column value could be smaller than the "size" column value if compression has been applied to the file system object in question.
Feature: Added a new option to the graph option window that allows the pie graph to hide pie slices that constitute less than XX% of the scanned total. This is really useful for keeping the pie graph labels under control, especially when scanning folders with a lot of small sub-folders. This now defaults to a value of "1%" - if you want to see every subfolder in the pie graph (as in previous versions), just change it to "0%".
Feature: Pie graph slices now show percentage information during folder scans (previously, percentages didn't appear until the folder scan completed).
Feature: The Windows used for product registration have all be re-designed. This includes the trial period reminder window, the registration key entry window, etc. The key entry window is now also accessible via the Help menu.
Feature: When a file system scan is completed, the status bar now shows the span of time the scan required (in HH:MM:SS format). This metric can be handy for scheduling scan jobs, etc. Note that this metric is affected by whether or not FolderSizes has scanned the folder recently (it caches scan data).
Feature: Labels on the "File Types" report graph can now be moved manually after the report has been generated. This allows you to tweak the label positions slightly prior to printing, for example.
Bug fix: Resolved a minor cosmetic issue with build 2.3.0.1 that caused the about box to display an incorrect number of days remaining in the software's trial period (applied only to users still in their evaluation period). The evaluation window that displays during application start-up did show the correct number of days remaining.
Bug fix: Resolved a minor defect that caused an incorrect number of "folders scanned" to appear in the status pane when accessing the same folder more than once.
Bug fix: Some pop-up window styles were interfering with the ability to switch back to FolderSizes with Alt-Tab. This has been resolved.
Bug fix: Quick key access has been restored to the detail list view and the "temporary files" report.
Change: The default colors used to indicate "hidden" and "compressed" folders and files were swapped to more closely match the colors used by Windows explorer. Blue is now used to compressed folders and files, and red is used for hidden folders and files. Of course, you can still change these to be whatever you like (any existing custom settings will remain in tact).

Version 2.3.0.1 (Released End of April, '04)

Feature:Added "owner" field to the XML export. This field is available only on Windows NT/2000/XP/Server 2003 platforms, and designates the owner (either a user or group) of the specified file or folder.
Feature: Increased the flexibility of the "Oldest Files" report considerably by adding two new options:
- The ability to indicate which file date/time stamp should be used for comparisons; you can now selected from "date modified" (the detault), "date created", or "date accessed".
- The ability to include only files older than a specified time period (in years, months, or days)
Feature: The time required to export large-scale FolderSizes reports in XML format has been reduced substantially (by 50% or more in most cases).
Feature: Added a new progress window that appears during XML exports. Very large reports may take a minute or two to export in XML format at full depth, and the progress window helps to convey the busy state of the system. Progress window is not shown during command-line based XML exports.
Feature: Added new totals to the top of HTML report exports. Now includes total files scanned, total folders scanned, and total scan size.
Feature: Added a new option for controlling the depth of XML report exports. By default, the XML export depth is set to 0, which equates to full depth (all folders and subfolders are traversed). Set this value to 1, for example, to export only the top-level folders associated with the current file system scan point.
Feature: Changed the information contained in the headers and footers of main detail view printouts. These areas are now populated with the report path (title), total files (left footer), total scan size (center footer), and total folders (right footer). This information is much more useful than what was provided previously. Note that you can *still* provide custom fields for these print areas (see "printing" in the options window) if you wish.
Feature: Now when exporting file report details to HTML format, the scan path is indicated at the top of the page.
Feature: The "owner" column of the main detail view (available on Windows NT/2k/XP/2003) is now populated even when scanning remote systems (via a mapped drive or UNC path). Previously, this column was only populated when scanning local drives or folders.
Feature: Introduced comprehensive new application fault detection, capture, and reporting system. Program crashes are extremely rare with FolderSizes (even in beta builds), but this system allows for excellent post-mortem analysis when needed.
Feature: Numerous performance improvements, particularly in the bar graph drawing code.
Feature: Added right-click shell context menu to the pie graph.
Bug fix: Resolved a minor problem in which an invalid export type error appeared when the user cancelled out of a file report export process.
Bug fix: Resolved an issue with the main graph windows not retaining the total size of all scanned file system objects in some cases.
Bug fix: Resolved a fairly rare bug in which sorting by the "owner" column (NT/2k/XP/2003) could cause an "out of memory" error.
Bug fix: FilterZip will no longer create zero-length zip files when no filter criteria match. Also improved overall validation of job input parameters.
Other minor improvements, documentation updates, and bug fixes.

Version 2.2.0.3 (Released Mid March, 2004)

Minor bug fixes and misc. preparations (e.g. modified splash screen version, etc.) for the official 2.2 release.

Version 2.2.0.2 (Limited Beta - March, 2004)

Feature: Added a new panel to the options window that allows users to customize the static text that appears at the top and bottom of printed "detail view" reports. By request.
Feature: Added a new command-line export switch called "text" that allows the primary detail view data to be exported in CSV format. By request. Note that the extension of the filename is important - ".csv" will export in comma-separated-values format, and ".txt" file export in tab-separated-values format.
Example: foldersizes.exe /path:"d:" /text:"my-csv-report.csv" /exit

Version 2.2.0.1 (Limited Beta - March, 2004)

Feature: Introduced a new graph-oriented file report for displaying distribution of file attributes. Provided usual array of menu and keyboard accessors.
Feature: Added new command-line switch called "attribs" for accessing the new "file attributes" file report.
Example: foldersizes.exe /path:"d:\temp" /filereport:"attribs"
Feature: Shell context menu extension was updated to provide access to "file attributes" report.
Feature: The pie graph view now reveals the amount of space consumed by files in the scanned folder. This is displayed as an additional pie slice labeled "[files]", followed by a percentage value.
Feature: Added the ability to right-click on the drive space pie graph and copy it to the Windows clipboard. By request.
Bug fix: Resolved a problem the main pie graph showing incorrect slice ratios under specific conditions.
Other minor improvements, documentation updates, and bug fixes.

Version 2.1.0.2 (Released Early February, 2004)

Change: Within the FilterZip system, comparisons of regular expression text against file names are now always case insensitive. Previously, the case sensitivity of the regular expression made it difficult to match all the files of a specific type (e.g. "TXT" was treated differently than "txt" and "TxT").
Feature: The user preference between pie / bar graph is now retained between program instantiations.
Feature: Added new command-line switch called "typesgraph" for accessing the new "file types graph" file report.
Example: foldersizes.exe /path:"d:\temp" /filereport:"typesgraph"
Feature: Shell context menu extension was updated to provide access to "file types graph" file report.
Feature: Added main menu accessors (and top-level keyboard shortcuts) for graph type switching (e.g. pie vs. bar).
Feature: File reports accessed by menu are now run immediately (e.g. without the need to press the file report start button) if a path in the folder browser is currently selected. Pressing the file report toolbar button will always bring up the file reporter without starting it automatically.
Feature: Several updates to the integrated help file. Also added context-sensitive (F1) help for individual file reports.
Other minor improvements and bug fixes.

Version 2.1.0.1 (Private Beta)

Feature: Better support for multiple monitors. Most UI components now appear in the proper virtual desktop when using multiple monitors. Selections in the Folder Browser window should also now work when the second monitor is located to the left. Some things, such as launching the default web browser, are handled by the shell and are still a bit quirky. But it should be better overall.
Feature: File reporter window (and it's child report progress window) are now centered to the main application window when they appear. Their sizes are still retained, but the positions are not. Overall I think this is a bit tidier.
Other minor cosmetic touch-ups.

Version 2.0.7.0 (Private Beta)

Feature: Added a file types graph tab to the file reporter window, which will be populated with a pie graph of file types consuming the most space. Graph support printing / previewing, and exporting (e.g. save as image).
Feature: Added the ability to switch the main graph view to a PIE graph. The pie graph exposes most of the same capabilities as the default bar graph, including export to file and clipboard, gradient background, etc. Also note that the pie graph exposes a "percentage of parent" value for each slice once a scan completes.
Feature: Added a new "/date" flag to the current set of supported command-line parameters. If this flag exists, it will force any output path names (such as those specified via "/html" or "/xml") to include the current date in mm-dd-yy format. For example, if you pass in an "/html" path of "d:\temp\test.html" and include the "/date" flag, the output path will be transformed into "d:\temp\test_01-03-04.html" (only using the proper current date, of course). This is useful when you need to schedule daily report generations and also want to output them into a common folder.
Example: foldersizes.exe /path:"d:\temp" /html:"d:\temp\myreport.html" /date
Feature: Now using a highly optimized global cache for all system image list icons. This improves the performance of scrolling and item population in any list that contains file shell icons.
Feature: Added vertical text labels to the bottom graph view toolbar to make those functions more intuitive, and to emphasize the new ability to switch between pie/bar graph views.
Feature: Added a new "file reports" options panel (accessible via options button on main toolbar). Two new supported settings allow users to control the sizes of the "largest files" and "oldest files" reports.
Feature: Added a new "/graphtype" flag to the current set of supported command-line parameters. If this flag is present in the command line input, it will switch the graph type to either "bar" or "pie" prior to any export processes taking place. So, for example, if you wanted to export an HTML report via the command line, but prefer to have a pie graph (versus the default bar graph), you can do something like this:
Example: foldersizes.exe /path:"d:\temp" /html:"d:\temp\myreport.html" /graphtype:"pie" /exit
Bug fix: Exclusions button on file reporting window was not being moved properly when window was resized.

Version 2.0.6.0 (Released Mid January, 2004)

Bug fix: Shell context menu extension was not working properly on legacy Windows operatings systems (WinNT, 95). This has been fixed.
Bug fix: Resolved a problem where, in some circumstances, the detail view would fail to refresh after a file was deleted (either via the context menu or delete key).
Change: These release notes are now included with each installation of FolderSizes, and are accessible directly via the help menu.
Other minor cosmetic changes and bug fixes.

Version 2.0.5.0 (Private beta build, not released)

Feature: When exporting a folder report in HTML format, the bar graph image is now saved as "<reportname>.jpg", rather than just "graph.jpg". This makes exporting multiple HTML reports to a single folder more managable, particularly when using the command line.

Version 2.0.4.0 (Released Public Beta Jan. 4th, 2004)

Bug fix: Resolved a problem that would cause file reports performed against CDROM / DVD media to fail in some instances.
Bug fix: Resolved minor defect in navigation history system involving virtual folders without literal file system paths.
Change: Changed default graph gradient background drawing mode to "forward diagonal".
Feature: FolderSizes now automatically refreshes the folder browser and drive space panes as required when removable and/or mapped network drives are added to (or removed from) the system.

Version 2.0.3.0 (Released Public Beta Dec. 27th, 2003)

Bug fix: Repaired a memory leak that could occur when scanning CDROM drives. Leak was introduced in the 2.0.2.0 beta build.
Feature: Improvements to the speed and scalability of the file report generator "folder tree" dialog.
Bug fix: Repaired minor problems with the way unknown "last accessed" file system dates were being handled.
Bug fix: Repaired a minor problem with the primary graph label that occurred directly after a file report was generated.
Bug fix: Resolved a few drawing bugs in certain list controls.
Bug fix: Resolved a problem where, in some rare instances, an exception would occur when rapidly switching between scan paths in the folder browser pane.
Feature: Excluded folders are now also honored by file reports. A new button was also added to the file report dialog for manipulating excluded folders.
Change: On the file report dialog, buttons for printing and exporting data are now always enabled. If they are clicked prior to report data being available, a note to this effect will be displayed. Previously, the buttons would be disabled when no report data was available - the change was made to minimize confusion and provide specific feedback (as well as improve consistency between dialogs).
Feature: By default, FolderSizes will no longer follow reparse points (e.g. mount points and symbolic links, also known as directory junctions) during normal folder scans, file report generation scans, and FilterZip scans. A new "scanning" option page was added (see tools | options) for re-engaging this option should you wish it.
Feature: Vastly improved the functionality and customization potential of the drive space panel. A new set of options (see tools | options) has been defined that allow the drive panel to display information on non-fixed drives (e.g. removable, network, etc.). You can also selectively ignore specific drive letters, control the auto-refresh timing, and more. Also added the ability to refresh the drive panel manually (see view | refresh drive panel) in case auto-refresh is disabled.
Bug fix: In the file type report, extensions were erroneously being sensitive to the case (e.g. upper or lower case) of the file extension characters. In other words, "txt" was being treated separatedly from "TXT" - they should be treated the same (and are now).
Feature: File report list controls no longer show "grid lines". This was done to improve consistency throughought the program, and to eliminate a problem with grid line artifacts appearing in list controls in some instances.
Feature: Several minor changes to toolbar and menu layouts. Added toolbar buttons for accessing certain display functions. Added status bar helper text for a variety of menu items that were missing them. Altered certain icons to better reflect their functions.
Feature: Added numerous additional hotkey combinations for functions such as exporting, user interface item display, etc.
Bug fix: Fixed a crash that could occur when switching to the "file type" report in the file report dialog.
Change: Updated splash screen to reflect the new version number (v2.0).

Version 2.0.2.0 (Released Public Beta - Dec. 17th, 2003)

Feature: Added the ability to select and act upon several files or folders at once (with the context menu) in the primary detail view.
Feature: Drive pane "tool tips" were re-worked. Now when you hover the mouse over a drive, a pop-up window will reveal a range of associated volume information such as filesystem type, volume label, etc.
Feature: FilterZip progress dialog can now be resized. The progress dialog list columns are now "sticky" (their sizes and positions will be retained between window displays).
Feature: Performed a detailed review of window control tab orders, keyboard access (shortcut) keys, etc. For example, the delete key now works on files and folders in the main detail view, the path bar and "go" buttons now have accessors, etc.
Feature: The path history mechanism (which allows the back and forward arrows to work, among other things) has been refactored for improved robustness. Now works regardless of the input path, and is no longer reset when folder browser nodes are deleted.
Feature: Added an "owner" column to the detail folder/file list view. Note that this column will ONLY appear on the Windows NT/2k/XP class of operating systems (which support the concept of file and folder ownership).
Feature: Added the ability to switch between several file size display options. Users can now choose between displaying file sizes in GB, MB, KB, bytes, or "automatic" mode (which chooses the file size display type based upon the file size itself). Version 1.x provided only the automatic mode. This setting, which is accessible via the view menu, will be honored by every file size display mechanism in FolderSizes (even the graph tool tips).
Bug fix: Fixed the known defect in the 2.0.1.0 beta release that prevented support for NT4 and Windows 95. Both of these older operating systems are now supported again (just as they were in v1.x). The only minor caveat is that the "Empty Recycle Bin" shortcut is disabled for these systems, because their APIs do not support programmatic access to that function.
Bug fix: Fixed a bug in the 2.0.1.0 beta that caused scroll bar tracking problems in the primary graph pane when very large data sets were being displayed (e.g. large drives scanned with maximum subfolder display depth).
Change: Renamed the shell context menu extension DLL, due to conflicts with longer names on the Win9x series of operating systems.
Numerous other minor improvements and optimizations.

Version 2.0.1.0 (Released Public Beta - Dec. 10th, 2003)

Feature: Introducing FilterZip technology, a powerful new way to free hard disk space. FilterZip allows you to combine advanced criteria-based filtering and recursive folder / file matching to zip files across multiple folders. Tell FilterZip where to start, define your criteria, and let it do the dirty work for you. Offers saving / loading of FilterZip jobs to and from disk, a "test run" mode for match confirmation, and powerful regular expression based filename filtering (among other criteria).
Feature: Users can now exclude specific folder paths from scans. New toolbar button and menu items were added to access the folder exclusions editor
Feature: Added "folder insight" popup tips to the primary bar graph. You can now hover over a bar or the associated text label and view a popup window that shows the full folder name, its size, and the number of files it contains (in the specified number of subfolders).
Feature: The detail list view will now show large folders in bold. This feature can be customized through the options dialog (display::detail view), where it can disengaged or customized in terms of what percentage of the parent a folder must meet or exceed in order to be considered large.
Feature: A brand new file report has been introduced for the discovery of duplicate files. The new report allows for the location of duplicate files as determined by a variety of combinatorial criteria, and can also be filtered by file size. Results can be exported to HTML format.
Feature: The main report contents can now be exported to XML format (see the export selection within the file menu). XML reports are generated all full subfolder depth (relative to the current folder scan path).
Feature: Added option to allow the user to instantly switch the subfolder display depth. By default, FolderSizes uses a subfolder display depth of 1, which means that when you select a drive or folder in the folder browser, only immediate subfolders are displayed in the detail and graph panes (at which point you can drill into them, etc.). Now, you can display any level of subfolder depth in the detail and graph panes. Just keep in mind that full depth display can produce some very large data sets.
Feature: FolderSizes now supports command-line execution with parameters. Parameters are not case sensitive. Note that passing command line options into BP FolderSizes will automatically suppress the display of the splash screen and the welcome wizard (if they are configured to display normally). The following command line parameters are supported:
- A "path" parameter, which must exist if any other command-line operations are to be executed. An example which would allow you to scan the temp folder on your D drive would look like:
  Example: foldersizes.exe /path:"d:\temp"
- An "html" parameter, which will generate an HTML report on disk once the scan is completed. You must provide a complete path for the HTML report file, like this:
  Example: foldersizes.exe /path:"d:\temp" /html:"d:\temp\myreport.html"
  Note: HTML reports can be generated only for normal scans, and not file reports, which are described below.
- An "xml" parameter, which behaves almost identically to the "html" parameter described above. Except, of course, that it saves the file out in XML format.
  Example: foldersizes.exe /path:"d:\temp" /xml:"d:\temp\myreport.xml"
- A "filereport" parameter, which tells FolderSizes to immediately launch a specific type of file report. The "filereport" flag must be followed by one of the types listed below.
  Example: foldersizes.exe /path:"d:\temp" /filereport:"largest"
  - "largest" - largest files in the scanned folder
  - "oldest" - oldest files in the scanned folder
  - "types" - file types in the scanned folder
  - "temporary" - temp files in the scanned folder
  - "duplicate" - duplicate files in the scanned folder
- An "exit" parameter, which will cause FolderSizes to exit once all the command line scanning options are completed. This allows for the generation of an HTML report (for example) on a scheduled basis, with FolderSizes automatically terminating in between executions. Note: "exit" cannot be used in conjunction with the "filereport" parameter (it will be ignored in this case).
Feature: Added shell context menu integration. Right-clicking on operating system folders will now produce a FolderSizes menu option, the submenu of which offers access to either a normal folder scan, or any of the file report types.
Feature: Any file report type can now be individually enabled or disabled. When file report types are disabled, they are eliminated from the scanning process. Disabling file reports that aren't needed can greatly increase the speed and memory efficiency of the scanning process, making all that much more flexible.
Feature: Added a graph tab to the drive space docking window. You can now switch to the graph tab whenver you'd like to see a pie graph representing used/free disk space on the selected drive.
Feature: Added auto-completion functionality to the main window "path" edit/dropdown box, as well as the path box in the file reporting window.
Feature: The report generation dialog window can now be resized. Window size and position are retained between instantiations. Window can also now be maximized.
Feature: Files with the attribute FILE_ATTRIBUTE_TEMPORARY can now be included in the temp files report.
Feature: Extended the tool tips provided on the temp file report window.
Feature: File reports can now be exported to HTML format. This is in addition to the existing comma-separated and tab-separated export formats.
Feature: The general dimensions and layout of the file report window have been improved and extended.
Feature: Extended the default temp file match mask (it now includes ".$$$" and ".old") in the temp file report. Existing installations will not be changed.
Feature: Added a shortcut to the tools menu for accessing the Windows network drive mapping facility.
Feature: Added ability to manually refresh the folder browser pane (from the view menu).
Feature: Added a "last access" column to the upper-right folder detail view.
Feature: Improved visual feedback indicators when dragging and dropping folders from Explorer into the FolderSizes detail view.
Feature: Added a shortcut to the tools menu for emptying the Windows recycle bin.
Feature: Certain system-level folders (such as "system volume information") can now be scanned successfully by FolderSizes, as long as the current user has Administrative or Backup Agent access rights.
Feature: There is now an option in the configuration dialog to globally disable tooltips (the little balloon hints that appear when you hover over various controls). Disabling them isn't generally recommended, especially since it also disables tool tips for graph elements. But the choice is now yours.
Feature: The explorer context menu is now supported within the bar graph view.
Feature: Significant improvements in the performance of the primary bar graph drawing code. It is now possible to view very large data sets in the graph without any real performance degradation. These optimizations will help support an upcoming feature that will allow the user to define the current subfolder display depth, which can produce very large graphs.
Feature: Altered the layout of the primary application toolbars. Minor changes to certain buttons (and their positions), and the file path drop-down box is now docked beneath the buttons.
Feature: Added a new top-level menu for sorting. FolderSizes has always allowed for sorting of columns by clicking a column name (clicking twice to reverse the sort order). This can now also be done via the main application menu.
Feature: The explorer shell context menu that appears when you right-click a folder within the folder browser or detail view now contain a special FolderSizes submenu that provides quick access to file reports. When initiated in this way, file reports will begin scanning the specified directory immediately when the report window appears.
Feature: Several improvements to the application status bar layout. Also added a new "folders scanned" status bar pane, which provides yet another scan progress indicator.
Feature: Now showing version information right in the main window title bar (by request).
Feature: Improvements to direct input path preparation / scrubbing logic.
Feature: Numerous cosmetic changes to various windows and dialogs to make them sexier and more informative.
Feature: Now displaying "finger" cursor over graph bars that can be interacted with (e.g. double-clicked or hovered over).
Feature: The error reporting capabilities that are available during normal folder/drive scans are now available during "file report" scans. If one or more errors occur during a file scan, the user will now be prompted to review them. The error report dialog that results shows what errors occurred with a textual explanation of each.
Feature: Numerous improvements to overall application performance.
Feature: The help system has been more tightly integrated with the FolderSizes user interface. The trend is toward help buttons or menus that are located close to where they're likely to be needed. Most dialogs can now also use the F1 button to call up the help file in context.
Bug fix: Reports toolbar button is now disabled during folder/drive scans from within the folder browser pane. Minor issue.
Bug fix: Resolved defect in "% of parent" detail view column when all folders were empty (e.g. zero byes in size).
Bug fix: Resolved an access violation that could occur if the primary window size was made to be extremely small (so that nearly every window component was hidden).
Change: Changed the "last access" and "last modified" columns of the detail report to exclude the time (e.g. only show the date). This is primarily a space-saving measure that allows for more attractive printed reports and on-screen viewing. Times were retained on the file reports.
Updated: Extensive updates were made to the FolderSizes help files to accomodate the new features mentioned in these release notes.

Version 1.5.0.0 (Released October 16th, 2003)

FolderSizes has been officially re-branded as BulletProof FolderSizes. With this change, FolderSizes becomes a commercial product, and is no longer freeware. This change brings FolderSizes into alignment with my vision for a more broadly marketed, professionally developed and supported software project.
Branding changes:
- Updated splash screen
- Updated welcome wizard
- Updated all internal product name references to BulletProof FolderSizes
- Updated readme file (readme.txt)
- Update license file (license.rtf)
- Updated product documentation
- Updated primary program icon
- Updated installer
Important: storage location for registry settings has changed slightly. Some preferences may be lost during the upgrade to this version of BulletProof FolderSizes. The impact of this should be fairly minor (e.g. related primarily to window sizes, etc.).
Added registration / license support system. Details are as follows:
- New installations without a registration key default to a 30-day trial period.
- BulletProof FolderSizes is fully functional when running in evaluation mode.
- If BP Foldersizes is not registered within 30 days of initial installation, it will cease to operate until a valid registration key is entered.
- The "about" box now displays license / registration information.
- Minor upgrades to BP FolderSizes will be free (existing registration keys will continue to work). Major version upgrades (e.g. from 1.x to 2.x) will require a new registration key.

Version 1.4.0.0 (Private build - not released)

Added the ability to double-click on a drive path in the drive space panel in order to initiate a scan on that drive.
Added tooltips to the drive space panel indicating the above capability.
Altered drive panel refresh timing so as to avoid a refresh while the panel has the mouse cursor. Will prevent refreshes while the user is attempting to double-click (or right-click) a drive path to take action on it.
Resolved a defect regarding synchronization of selected scan path with history combo box.
If the user cancels the welcome wizard presentation, they are now prompted on whether they'd like to see it again the next time FolderSizes starts.

Version 1.3.0.0 (Released September 27th, 2003)

Added support for NT4 (service pack 6 with Internet Explorer 5.0 or greater).
Removed the "hot tracking" style on the primary detail view. This was not consistent with the report lists or the need to double-click a folder to drill into it.
Added support for UNC paths in the toolbar "path" combo box. Now you can enter network paths directly - as long as they can be accessed without error, they will be scanned by FolderSizes. Note that FolderSizes currently will not prompt for authentication details if they are required to access a network share (make sure you auth in advance of running the scan).
Added support for dragging and dropping folders into FolderSizes from Windows Explorer (or Windows shell). Simply drop a folder name onto the detail view to initiate a FolderSizes scan.
Vastly improved handling of errors that occur during the folder/drive scanning process. Now if an error occurs during scanning, once the scan has completed a small warning icon/text will be displayed in the status bar, prompting the user to double-click that location for further details. The folder scan error details window will reveal the path of each scanning error and the cause of the error.
Resolved a problem with FolderSizes reporting incorrect sizes for very large files (over 4GB).
Resolved a problem where invalidate file date/time values would cause FolderSizes to throw an odd error and stop scanning a folder.

Version 1.2.0.0 (Released September 16th, 2003

Now formatting all date/time strings according to Windows locale settings.
Several changes / improvements to the appearance of FolderSizes-generated HTML reports.
The "largest files", "oldest files", and "temp files" reports now all allow for multiple items to be selected (by using the ctrl or shift key). When combined with the right-click context menu, this now allows for the deletion of multiple files.
Remedied a minor horizontal scrolling glitch in the graph view.
Added a cool new collapse/restore capability to the horizontal split (between the detail view and the graph view). Clicking inside the centered control box will collapse the graph view, showing only the detail view. Clicking it again will restore it to its former position. Very handy for when you need to see a large number of folders (and/or files) in the detail view.
The previous welcome screen has been replaced with a much more involved wizard that introduces the basic concepts of using FolderSizes. The wizard presents screenshots, formatted text, and options.
Improved the logic used to generate the primary graph title. For drives (including mapped drives), it will now use a title like "share on 'desktop' (Z:)" (rather than just the drive letter). This is much more useful when you're generating reports against mapped drives, for example.
Resolved a defect that caused the primary HTML export cascading style sheet not to be copied into place during installation.
Made minor adjustments to menu labels and hover text.

Version 1.0.3.0 (Released August 31st, 2003)

No longer showing "control panel" in the folder browser tree. This was extraneous from a folder browsing perspective.
Slight improvements to the "no items to display" text that shows within empty controls.
Report path history is now saved between application instances.
Report path combo box will now accept the direct entry of a folder path.
The "view folder files" option is now switched on by default. Folder files will be displayed in the detail view (top right pane), but the graph view (bottom right) will just display folders.
Detail list view sort column and sort direction are now remembered between program launches. Since the lower-right graph is automatically sorted in sync with the detail list view, it's sort properties are retained as well.
Now sorting the directories presented in the Folder Browser panel. It seems that on 9x platforms these weren't being naturally populated in a sorted order (as they are on 2k/XP).
Added the ability to choose the fonts used to draw the lower-right hand graph.
Added some missing tool tips to the graph display properties window, and resolved a defect that prevented their display.
Modified the graph display logic so that folders containing only files will still report an overall size within the graph label / title.
Made several other improvements to the graph drawing code. Eliminated a couple of computational artifacts, improved the graph bordering logic, improved use of anti-aliasing, and made a few other minor tweaks. It's lookin' pretty groovy, I think. ;-)
Several minor defect resolutions.

Version 1.0.2.0 (Released August 26th, 2003)

Added a "% of parent" column to the detail list view.
Added a brand new file report type called "Temporary Files". This new report will provide you with insight as to location of temp files on your system, as well as their size. This is done via a temp filename "mask" which is compared against each scanned filename; those that match the mask are included in the report. Since the temp report list can be burdened by a very large number of files (for example, if you scan your entire C drive, you may found many thousands of temp files), the list sorting and containment algorithms for this report have been highly optimized.
Many new memory and performance optimizations.
Increased horizontal size of file reporting window slightly to accomodate plans for future capabilities.
Changed default control focus of the report generator dialog to the path combo box. Also changed default button to the "start scan" button.
The FolderSizes graph view can now be used to navigate child folders, just as the list view can. Click a graph bar to highlight the corresponding entry in the list above. Double-click a graph bar to drill into the corresponding subfolder.
Extended the online help, as required, to accomodate the changes to this build.

Version 1.0.1.0 (Released August 16th, 2003)

Now when a folder scan completes, the result graph shows the total size of the scanned folder as part of the graph label.
Plugged a system handle leak that occured during file report generation.
Modified the formatting of the "files" and "folders" columns in the main folder/file list to use thousands separators.
Numerous memory optimizations.
Added keyboard scroll support to the graph pane. Now supports up/down arrows, page up/down, and home/end.
Revised the help files to bring them up to date with the current build.
The uninstaller now cleans up registry entries created by FolderSizes.

PRIVATE NOTE: Version 1.0.1.0 adds beta expiration code that will allow the program to run for no longer than 120 days. Warnings to this affect will begin after 60 days (e.g. 60 days left), and "firm warnings" will begin after 90 days (e.g. 30 days left). Firm warnings attach a different query string symbol to the URL triggered by the expiration dialogs "home page" button (that's currently the only difference between "firm" and "normal" warnings).

Version 1.0.0.9 (Released August 10th, 2003)

Added new text export capability. The primary folder list contents can now be exported as either comma or tab separated values (.csv and .txt file formats, respectively).
Added new export options (see tools | options | export) for text exports. User can choose whether or not folder list headers are included in export, as well as whether exported list fields are quoted.
Added text export capability to all of the report types contained with the report generation system (e.g. "largest files", "oldest files", etc.). Reports can be exported as either comma or tab separated values.
Minor changes to the arrangement of certain top-level menu items.
Added abilty to export the list view contents to the clipboard (as comma separated values).
Graph / list view splitter position now restores correctly when the application re-starts.
Added new graph display section to options dialog. Can now determine whether gradient effect is used for the background, and can choose which colors are used.
Altered the behavior of the banding graph in the "largest files report". Previously, hovering over a specific band would reveal the corresponding file name in a read-only edit box just beneath it. In this version, the edit box has been removed. To replace it, you can now hover over a band graph to get a tool tip which reveals the file name. As before, a band can still be clicked to find the corresponding entry in the tabular list.
Graph display options now allow user to select the direction of the gradient graph background. Choose from "vertical", "horizontal", "forward diagonal", or "backward diagonal".
Numerous improvements (speed optimizations, color cycling algorithm tweaks, etc.) within the banding graph drawing code.
Resolved a problem with initiating reporting scans on Win9x/ME in certain environments.

Version 1.0.0.8 (Released August 6th, 2003)

Resolved minor defect relating to the folder explorer history buffer.
Now highlighting the selected banding graph item in the "largest files" report when clicked.
Several performance enhancements and memory optimizations.
Normalized the color palette used across the various graphing objects.
Added new toolbar button for quick access to report generator.
Added ability to save the "folder tree" (as a text file) that's created during report generation scans. It seems that people really like these. :-)
Added a few more tool tips here and there.

Version 1.0.0.7 (Released July 24th, 2003)

Column sizes for all reports (largest files, oldest files, file classes, etc.) are now saved. If you resize them, they'll be the same size next time you bring up the reporting window.
Report window lists now shade the background of the sorting column.
The "generating report" window that displays when a report scan is run (see the view | reports menu) now displays a "tree" of the folders that it encounters during the scan.
The "generating report" window is now resizable, and retains its position and size between instantiations.
Greatly improved (e.g. shortened) post-scanning report generation timeframe by initializing shell icons on the fly (as the lists are scrolled).

Version 1.0.0.6 (Released July 20th, 2003)

Double-clicking on a report filename will now open it by default (in addition to the shell context menu that's already available).
Shortcut to the FolderSizes help file is now added to the program group during installation.
Further reduced the height of the report screen window to better accomodate 800x600 resolution.
Resolved a defect that, when copying the main graph image to the clipboard, caused only the visible portion of the graph to be copied. Now, the entire image is copied, even if part of it is off screen. Thanks to Dave Collingwood for bringing this to my attention.

Version 1.0.0.5 (Released July 15th, 2003)

Resolved fairly obscure defect that could cause an abnormal termination upon app shutdown.
Resolved minor issue in which the file type data cache would not be expunged at the correct interval.
Modified the reporting dialog slightly to better accomodate lower resolutions.
Finished up a few remaining control tooltips.
Shell context menu file deletions from "largest" and "oldest" file reports now refresh list contents properly.
Minor tweaks to the report list column sorting logic.

Version 1.0.0.4 (Released July 12th, 2003)

Yet another fairly radical re-factoring of the FolderSizes reporting systems. Reports can now be run at any time and implement their own fine-tuned drive/folder scanning algorithm. The graphical interface for reports has also changed extensively - all reports are now contained within a single window, and you can switch between them at will. All reports are also generated at the same time, when any drive or folder is selected for report generation. Previous report paths are also "remembered" in a drop-down edit box, for quick access later.
A new "oldest files" report has been introduced. This report (perhaps obviously) finds the oldest files within the folder or drive path provided by the user. The output is integrated with the new reporting window, described above.
All button tool tips have been enhanced and re-written for maximum clarity.
Extended the set of keyboard accelerators (shortcuts) available.
The product documentation has been updated and extended to cover the most recent set of changes. The docs were also re-organized.

Version 1.0.0.3 (Released July 5th, 2003)

Changed a variety of internal program hyperlinks to reference the new foldersizes.com website.
Made extensive changes to compiler optimizations for increased overall speed.
Implemented new folder enumeration cache. This system allows for the caching of previously scanned file system objects, making for a much quicker browsing experience when exploring cached folders and subfolders. Using the refresh button (toolbar button or menu item) will force an invalidation of the cache for the current folder node (and all of its children).
Implemented numerous memory optimizations.
Made numerous improvements to the folder enumeration engine.
Resolved defect that was causing the text sorting in the "largest files" report list control to be case-sensitive.
The way in which folder reports are generated has changed quite a bit. Previously, you needed to execute a folder scan prior to accessing a report. This is no longer true; reports are now generated separately from "general" folder scans. This helps to minimize the impact of the new caching mechanism, and also provides greater flexibility for the end user.
