Strengths and considerations
Strengths
- Live maps and a staged removal collector
- Content-based duplicate search
- SSH and rclone-backed cloud storage
Considerations
- Uses a cross-platform Rust interface rather than SwiftUI
- Permanent deletion and secure erase require deliberate review
- Cloud/SSH actions depend on provider and remote-system support
How cleanup works
Collector offers Trash, permanent removal, secure erase, or backup before deletion. 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.
