WinDirStat is a free, open-source disk usage statistics viewer and cleanup tool for Microsoft Windows. It scans drives and folders and visualizes storage usage through sortable directory lists, extension statistics, and an interactive treemap, with built-in search, duplicate detection, and cleanup actions.
Use cases
- find out what is taking up disk space on my Windows PC
- visualize folder sizes as a treemap
- find and delete large files
- detect duplicate files by content hash
- clean up disk space and empty the recycle bin
- monitor file system changes in a folder
- export a disk scan report to CSV
When to choose
- you need a visual, interactive overview of disk usage on Windows
- you want built-in duplicate detection and cleanup actions in one tool
- you need fast NTFS scanning with multithreading and elevated privileges
- you want a portable, free, open-source disk analyzer
When to avoid
- you are on Linux or macOS (use tools like ncdu, KDirStat, or GrandPerspective instead)
- you need automated, scriptable disk reporting without a GUI
- you need network drive or cloud storage quota analysis as a primary feature
