About This Software

Fat File Finder scans your drives and gives you a clear, visual breakdown of exactly what's taking up your storage.

The large interactive treemap takes up most of the screen, giving you an at-a-glance view of your entire drive. Bigger blocks mean bigger files, so the worst offenders are impossible to miss. A detailed file list sits alongside it, letting you sort ascending or descending by size so you can zero in on the biggest space hogs or track down the smallest clutter.

Want to see what Windows has been hiding from you? Toggle on hidden files to get the full picture of what's really on your system.

No digging through File Explorer, no guessing. Just find the big stuff and delete it.
