Strengths and considerations
Strengths
- Switch between radial charts and treemaps
- Logical size, allocated size, or file-count modes
- Export snapshots and animate changes across a sequence
Considerations
- Mobile scans cover locations accessible through Files
- Snapshots record inventory, not backed-up file contents
- Historical snapshots need a fresh scan before cleanup
How cleanup works
Preview, reveal, or move selected items to the bin. Confirm each file’s path and purpose before removing it. Items in Trash still occupy storage until it is emptied.
How NullDisk compares
A native Mac disk analyzer with radial and treemap views, SSH/cloud sources, and development cleanup. Consider it for Git-aware development cleanup or a workflow spanning local, SSH, and cloud storage. The separate CLI provides terminal browsing and structured reports.
All direct Mac features are free with reminders; an optional one-time license removes them.
NullDisk has no content-based duplicate finder. Its Mac app sends anonymous usage telemetry; read the privacy policy if that affects your choice.
