FolderSizes v4.5 is Released

FolderSizes v4.5 is now officially out of beta, and has been released to the general public.

I’m extremely excited about this new release. It contains a wealth of new capabilities, including (but not limited to) Unicode support, command line access to the search facility, improved file system object sorting, numerous search system improvements (including better support for finding folders – including empty ones, a more granular file mask exclusion mechanism, etc.), numerous user interface improvements, and a variety of performance enhancements.

We’ve also decided to drop support for Win9x based systems (including Windows 98 and ME). At this point, the limited use of FolderSizes on these platforms is simply no longer worth the extra development and testing time required to support them.

Download the new release from our product download page. Full release notes are available here. The upgrade is free for all existing v4 license holders. And if you’re still using an older version, this is another great reason to upgrade.

BTW, those of you who know me are probably aware of how seriously I take the usability and appearance of our software products. Aside from core features, this new release of FolderSizes has a broad array of user interface enhancements, a new application icon, updates to the help file, and even new graphics in the product installer. Let me know what you think!

Duplicate File Detective 2.0 – Released!

The next generation of our powerful, professional-grade duplicate file management software, Duplicate File Detective 2.0, has been released.

I’m really excited about this new version. The software itself has lots of great new features, such as an integrated image preview panel and byte-for-byte file content matching, plus we have a brand new website and product logo.

  • Image preview (docking) window
  • Numerous extensions to smart marking system, including pattern matching

FolderSizes v4.1 and the File Extension Researcher

Today we’re releasing FolderSizes v4.1, an update with a sprinkling of new feature goodness and numerous performance optimizations. There are also a few minor bug fixes thrown in for good measure.

One of the new v4.1 features is something that I’ve actually been thinking about for a while now – a File Extension Researcher tool. As you’re probably aware, there is no central authority for file extensions, and it can sometimes be difficult to track down the source of file extensions that you encounter. Well, the FolderSizes v4.1 File Extension Researcher is designed to help.

As you can see from the first screen shot, the File Extension Researcher allows you to enter a file extension (e.g. “.pdf”, “.dat”, etc.) and provides two pieces of information in return. First, it shows the Windows shell file association, which largely controls how Windows itself responds to the extension. But for many extensions, Windows has no shell association whatsoever, and the second piece of information – a general listing of potential application matches – can help in those cases.

Additionally, you can click the Research Online button, which will launch your default web browser and pull up additional details on the extension in question. Currently, the source for this additional information is FILExt.com – an excellent website dedicated to this task.

You can click the View All Extensions button to see a complete listing of all the file extensions that FolderSizes knows about (over 23 thousand of them!). To keep things manageable, the extension browser window groups the extensions by leading alpha character, number, or symbol.

As an added convenience, the new File Extension Researcher can be launched by right-clicking any file listed anywhere within FolderSizes 4.1 (as long as the file has an extension).

There are lots of other goodies in the new FolderSizes v4.1 release (see release notes on the download page). This just happens to be one of my favorites. :-)

FolderSizes Version 4 is Released

Key Metric Software is proud to announce a major update to its powerful, network-aware disk space management software – FolderSizes 4.0.

This new release adds a wealth of new capabilities and improvements. Here’s a partial list:

  • Generate File Reports against multiple paths
  • Greatly expanded command line support
  • New “file name length” based search (and scan filtering) criteria
  • New “avg file size” and “attributes” columns in main exploration view
  • New ability to load / save scan-time filter definitions
  • “Size in bytes” is automatically appended to all detail view CSV exports
  • Optimized FolderSizes for use on Windows Vista
  • Improved drill-down capabilities in various File Report detail views
  • Extensive user interface enhancements
  • New switch for disabling / enabling the FolderSizes shell context menu
  • Expanded help system (better coverage of command line options, etc.)
  • Added printing and sorting capabilities to the “My Computer” view
  • New visual indicator for all “% of parent” detail view columns
  • Much more!

In addition to these improvements and new features, FolderSizes 4.0 contains dozens of smaller enhancements that work to greatly improve overall robustness and usability. Nearly every aspect of the application, from the low-level file system scanning engine to the rendering of graph bars, has been tweaked and optimized.

Note that FolderSizes 4.0 installs (and is licensed) separately from existing versions of the application. This allows current FolderSizes users to fully evaluate the new version before deciding whether or not they wish to upgrade (special upgrade pricing is available) – without disturbing their existing product installations.

Download the new FolderSizes 4.0 release now, and try it for yourself.
