Disk Atlas beta

Disk Atlas is nearly ready for release, but I'm still doing some final testing.

How Disk Atlas works:


Select a drive or folder to scan.


Explore the results of the scan.

The bigger the rectangle, the more space it's taking up. Light rectangles are folders, dark rectangles are files.
step 2
You can tell Disk Atlas to show only the biggest items, or to show smaller ones too.
You can navigate by going inside of folders.
If you find files or folders you don't want, add them to the trash. (You can restore items from the trash if you change your mind.)
Empty the trash when you've found everything you want to delete.
bullet point Analyze any connected drive, or specific folders.
bullet point Runs on Windows and macOS, and Linux.
bullet point Low one-time cost. No ads, subscriptions etc.
