WinDirStat, but 10x faster and on Mac too
FreeUpDisk is a free disk space analyzer for Windows and Mac. Same treemap concept as WinDirStat. Scans in under 30 seconds instead of minutes.
The #1 reason people switch from WinDirStat
WinDirStat can take 5–15 minutes to scan a large drive. FreeUpDisk uses a modern scanner that completes the same scan in under 30 seconds. Same treemap visualization, dramatically faster results.
Why people look for a WinDirStat alternative
WinDirStat is a classic. It was released in 2003 and introduced many people to treemap-based disk visualization. But it has limitations that have become harder to ignore:
- It only runs on Windows, no Mac support
- Scanning a large drive takes 5–15 minutes
- The interface looks like it was designed in 2003 (because it was)
- It hasn't had active development for years
FreeUpDisk solves all four. It uses a modern file system scanner, works on both Windows and Mac, has a clean interface, and is actively maintained.

How FreeUpDisk works
Scan your drive in under 30 seconds
Open FreeUpDisk and select your drive. It reads your entire file system using a modern scanner, no waiting 10 minutes like WinDirStat.
See the full treemap instantly
Your drive appears as a visual treemap - every file is a colored rectangle. Bigger rectangle = more space. You see what's large without clicking through folders.
Clean with confirmation
Click any rectangle to inspect the file or folder. Delete directly from the interface. Nothing is removed automatically - every action requires your confirmation.
