Unlimited Disk Usage

See exactly what is using your disk. Scan a folder, your home directory, or a whole volume, and watch the map fill in as the scanner works. There is no waiting for a full pass to finish before the big folders show up. FIVE WAYS TO SEE YOUR DISK Treemap: folders as nested rectangles, sized by what is inside them. Mosaic: every file as its own tile, colour-coded by type. Sunburst: concentric rings radiating out from the folder you scanned. List: everything sorted by size. Block map: defrag-style blocks coloured per app, with a size legend. RESULTS WHILE IT SCANS The scanner streams results as it goes, so the largest folders appear first. Switch between the five views at any time without rescanning. Drill into any folder, move back and forward, and rescan a single branch instead of starting over. Quick Access keeps Home, Desktop, Downloads, Documents, Applications, Movies, Music, and Pictures one click away, along with your recent scans. A MAP THAT STAYS CURRENT The view keeps refreshing as files are added, moved, and deleted, long after the scan has finished. What you are looking at is the disk as it is now, not as it was when you pressed Scan. WORK WITH THE FILES, NOT JUST THE PICTURE Quick Look a file, reveal it in the Finder, copy its path, or move it to the Trash. Drag folders in to scan them, and drag files out to use them somewhere else. Full keyboard navigation and VoiceOver throughout. ONE PURCHASE One purchase, and you can scan as many disks as you like. No account, no subscription, no in-app purchases, no ads, no analytics, and no tracking. Nothing leaves your Mac.
