Strengths and considerations
Strengths
- Configurable colors, masks, searches, and scan exclusions
- Quick Look, Finder integration, and file/folder deletion
- Save/reload scans and export text or images
Considerations
- Treemap rather than radial navigation
- Older macOS versions require an older release
- App Store updates can follow SourceForge releases later
How cleanup works
Delete files or folders from the view; review selection and deletion preferences. 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.
