Description
WinDirStat is a free, open-source disk usage analyzer and cleanup utility for Microsoft® Windows®. It scans a selected drive or folder, then presents storage usage through a directory tree, an extension list, and a colorful treemap that makes large files and space-heavy folders easier to identify.
The program is useful when Windows reports that a drive is full but the cause is not obvious. Instead of opening hundreds of folders manually, users can scan the target disk, click large treemap blocks, inspect file extensions by size, and decide which files or directories are safe to remove or move elsewhere.
Note: I have tested and used WinDirStat for the last five years. I installed and ran the program without any other issues on Microsoft® Windows® XP SP3, 7, 8, 8.1 and 10.

WinDirStat Features
WinDirStat combines several views of the same scan result. The directory list shows which folders consume space, the extension list groups files by type and color, and the treemap turns disk usage into a visual map where the biggest blocks represent the biggest files.
Cleanup is integrated into the workflow, so users can move from discovery to action without copying paths into another tool. Options for full-row selection, grid or stripe display, treemap styles, custom cleanup commands, and report settings make the program flexible despite its small installer and simple interface.

WinDirStat Review
WinDirStat remains valuable because it makes a common Windows problem visible. Checking each partition in File Explorer shows free space, but it does not explain which nested folders or forgotten downloads are responsible for the loss; WinDirStat answers that question quickly.
In prior use, the program scanned a 200 GB laptop drive in about a minute and a half, then made the largest files easy to locate through the treemap. Its interface is older, but the workflow is direct: scan, inspect the tree and colored blocks, confirm file locations, and clean up only what you recognize.
