About
DiskMate: Disk Space Analyzer & Cleaner for Mac
DiskMate is a native macOS app that shows what's taking up space on your Mac and helps you safely free up storage.
Scan your Mac, find large files, clear caches, remove duplicate files, and uninstall apps completely, all in one app
For a one-time price.
Mac storage full? See exactly where your disk space went
DiskMate scans your whole Mac, or any folder or external drive, and breaks down disk usage by folder, by file type, and by age. Sizes match what Finder reports, so you know what's really using your storage.
Disk space analyzer with visual maps
See your Mac's storage as a treemap, sunburst chart, icicle chart, bubble chart or ranked list. Click any folder to drill down and find what's filling your disk.
Clear cache and junk files on Mac safely
DiskMate sorts cleanup into two groups:
- Safe to clear: app caches, log files and the Trash, which apps rebuild on their own
- Worth a look: old downloads, disk images and large videos you might still want
You tick what goes, and everything moves to the Trash first, so nothing is deleted by surprise.
Duplicate file finder for Mac
Find duplicate photos, videos and documents. Every match is confirmed byte for byte with SHA-256 hashing, so only true copies are shown. Keep one and clear the rest in one click.
Uninstall apps completely on Mac
Dragging an app to the Trash leaves caches, containers, preferences, and logs behind in ~/Library. DiskMate finds these leftovers, shows each app's full footprint, and removes the app and its files together. It also lists the launch agents that start with your Mac.
Find large and old files on Mac
See big files you haven't changed in over a year, sorted by size. Search every scanned file instantly, and filter by kind, size, and last modified date.
Private and offline
DiskMate runs entirely on your Mac. There's no account, no uploads, and no analytics. Rescans are fast because only folders that changed are read again.
Frequently asked questions
How do I free up storage space on my Mac?
Scan your Mac with DiskMate, review what's safe to clear, tick it and press Clean. Everything goes to the Trash, so you can restore anything.
How do I find large files on my Mac?
Use DiskMate's Space view to rank folders and files by size, or search for everything over 1 GB.
Is it safe to delete cache files on a Mac?
Usually, yes: apps rebuild their caches when needed. DiskMate lists caches separately from your real files and moves them to the Trash rather than deleting them.
Is DiskMate a subscription?
No. It's a one-time purchase, and you keep it forever.
Which Macs does DiskMate support?
Macs with Apple silicon (M1, M2, M3, M4 and newer) running macOS 14 Sonoma or later.
