Desktop PCs and servers can quickly end up accumulating large quantities of unused, temporary, and duplicate files. Before you know it, you're out of drive space, backups are taking far too long to run, and users can't find the data they need when they need it. You need a visual, interactive software tool to help you manage disk usage. You need FolderSizes. FolderSizes is an award-winning, network-enabled disk space analysis tool. It can quickly isolate large, old, temporary, and duplicate files, or even show file distribution by type, attributes, or owner. All with multiple export formats, command-line support, shell context menu integration, and much more.

FolderSizes goes far beyond the capabilities of competing solutions by combining several tools into one: Disk Space Explorer - Awesome detail view, coupled with stunning graphical bar and pie graphs Duplicate File Report - Quickly isolate and manage duplicate files within any folder or volume Largest Files Report - FolderSizes can quickly show you which files are eating up the most space Oldest Files Report - Use your own criteria to find old files that may no longer be needed Temporary File Report - Eliminate temp file clutter left over from software installs, downloads, browsing, etc. File Owners Report - Discover which users are consuming the most space on local and network drives File Types & Attributes Reports - See the distribution of disk space by file type or attributes Drive Space Monitor - Instant, at-a-glance view of any local, mapped, or removable disk File Sizes, Names & Dates Reports...

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.
