Folder Size Reports offer powerful insight into disk space usage, providing you with a wealth of information for both folders and files, including:
•Name - The name of the file system object (file or folder).
•Size - Actual size of the file system object.
•Allocated - Size of the file system object on disk (includes cluster size computations). See details here.
•Files - Count of files associated with the object. When viewing a folder, this is the number of files it contains.
•Files (Immediate) - Count of immediate child files only (not including those contained within child folders).
•Folders - Count of all descendant folders (e.g. child folders plus their children, etc.) associated with the object.
•Folders (Immediate) - Count of immediate child folders only (not including those contained within child folders).
•Modified - Date the file system object last changed.
•Created - Date the file system object was created.
•Accessed - Date the file system object was last accessed.
•% of Parent - Percentage of the parent file system path this object constitutes.
•Attributes - Summary of file system attributes, using a combination of letters to represent each specific NTFS attribute (R = Read only, H = Hidden, S = System, D = Directory, A = Archive, N = Normal, T = Temporary, C = Compressed, E = Encrypted, O = Offline, I = Not indexed, P = Sparse).
•Avg. file size - Average file size.
•Depth - Depth of the file system object in relation to the root scan path.
•Type - A textual description of the file or folder type.
•Owner - Name of the file system object owner.
•Full Path - The complete file system path
•Calculated Modified, Created, and Accessed - Click here to learn more about calculated date/time values.
•Relative Age - Shown in bar graph form, represents age of object relative to last modification date/time of its siblings (objects within the same parent folder).
•Path Len - The total length of the file system path in question.
•Name Len - The length of the immediate name portion of the file system path.
•Link Target - If the path represents a resolvable link (symbolic link or mount point), the link target will be shown here.
TIP: Not all columns are displayed by default. You can control which columns are displayed by right-clicking any detail view column header and selecting each of the columns you wish to have displayed.
Other Detail View Features
One of the many compelling features of the FolderSizes detail view is that it updates dynamically, as a file system scan progresses. Just navigate to a file system folder or drive to begin an analysis.
You can right-click any folder or file in the detail view to gain access to a context menu containing many useful functions.
Double-clicking a folder name in the detail view will cause FolderSizes to drill down into that folder, allowing you to explore it further (files are opened with their default program handler when double-clicked).
A single click (with the left mouse button) in any of the detail view column headers will cause FolderSizes to sort by that column. Click the same column again to reverse the sort order. Note that the graph view display is always sorted in the same order as the detail view.
Folder and file entries in the detail view are color coded according to their file properties. For example, by default system folders and files are colored red, and compressed objects are colored blue. The colors can also be customized within the detail view section of the options window.
The detail view also has a wealth of display modes from which you may select. Select the View tab within the application ribbon bar to explore some of these options, including subfolder display depth, file size format, and much more.
