Unlimited Disk Usage
See exactly what’s on your drive and where the space went.
macOS
Scan a folder, your home directory, or a whole disk, then explore every byte as a treemap, mosaic, list, sunburst, or defrag-style block map. Results appear while the scan runs.
Results appear during the scan, so large folders surface before the pass finishes. The native scanner keeps every view updated as it walks the file system.
Five ways to see your disk
- Treemap — folders as nested rectangles, sized by what’s inside.
- Mosaic — every file as its own tile, color-coded by type.
- Sunburst — concentric rings radiating out from the scanned root.
- List — everything sorted by size.
- Block map — defrag-style blocks colored per app, with a size legend.
Highlights
- A living map — the view keeps refreshing as files are added, moved, or deleted, long after the scan finishes.
- Drill down without starting over — enter any folder, move back and forward, and rescan a single branch.
- Quick Access — keep common folders and recent scans one click away.
- Work with files directly — use Quick Look, Reveal in Finder, Copy Path, or Move to Trash; drag folders in to scan them and files out to use them elsewhere.
- Native on Mac — the interface, scanner, and rendering support full keyboard navigation and VoiceOver.
