WinDirStat (Windows Directory Statistics) is a powerful disk usage statistics viewer and cleanup tool for Microsoft Windows. It displays a visual treemap representation of your hard drive that makes it easy to identify large files and folders consuming disk space.
The program scans your drives and presents the results in three useful views: a directory list similar to Windows Explorer, a treemap showing file sizes as colored rectangles, and an extension list grouping files by type. This makes WinDirStat an essential tool for disk space management and cleanup.
Each color in the treemap represents a different file type, making it incredibly easy to spot what's taking up the most space on your drives. Whether it's large video files, old backups, or forgotten downloads, WinDirStat helps you find and manage them efficiently.
