What you get

See where your storage goes and remove files you no longer need.

DiskMap gives you a visual breakdown of what's taking up space on your Mac. Instead of checking folders one by one in Finder, you can spot the largest files and folders, then explore them layer by layer with sizes visible throughout. That helps you locate old downloads, forgotten archives, oversized caches, and duplicate folders worth reviewing.

Before removing anything, you can preview it with Quick Look and decide whether you still need it. You approve every deletion, and system files are marked and protected, so you aren't handing cleanup decisions to an automatic process.

You can also check external drives, SD cards, network volumes, mounted disk images, and Time Machine drives. Your files stay on your Mac, with no telemetry or data sent elsewhere, and the app doesn't leave background processes running after your cleanup.

  • Find your largest files

    You can see which files and folders occupy the most space without checking each folder manually.

  • Review before deleting

    You can preview files with Quick Look and remove only what you explicitly choose.

  • Check storage beyond your Mac

    You can locate space-consuming files on external drives, SD cards, network volumes, and other mounted storage.

  • Keep cleanup under your control

    Your system files are marked and protected, and nothing is deleted automatically.

Best for

  • You need to make room on a nearly full Mac
  • You have external drives full of forgotten files
  • You prefer reviewing files before deleting them

Skip it if

You don't need it if you already know what's using your storage and can remove unwanted files in Finder.

From the developer

Pick a drive, hit Scan, and in seconds you know exactly where your gigabytes went. Found something you don't need?
