WinDirStat (Windows Directory Statistics) is a free and open-source disk space analyzer and cleanup utility for Microsoft Windows. It displays storage use through a directory tree, statistics grouped by file extension, and graphical visualizations. Its treemap represents files as colored rectangles whose areas are proportional to their sizes, allowing users to locate large files and directories. The program also includes duplicate-file detection, permissions analysis, storage-cost estimates, reporting, and deleted-file recovery.
