| Cleanup workflow | Collector stages items, then permanently removes them after confirmation and a cancellation countdown. It does not use macOS Trash. | Preview, reveal, or move selected items to the bin. |
| Reports and portability | The cited overview does not establish a portable scan-report format. Preserve paths or screenshots and check the current manual before migrating. | Export a snapshot and keep it: the developer documents JSON/TSV records that can be viewed in a text editor. NullDisk does not import these snapshots. |
DaisyDisk: what stands out
A good fit for Mac users who want a sunburst, cloud connections, and snapshot tools.
DaisyDisk: strengths
- Sunburst navigation with Quick Look previews
- Physical-size accounting for clones and hard links
- Cloud connections and macOS snapshot management
Considerations
- Mac app; no Windows or Linux desktop edition
- Full functionality requires a paid license after trial
- Some capabilities differ between direct and App Store editions
Disk Graph: what stands out
A good fit for people who want saved storage history or a companion on iPhone/iPad.
Disk Graph: 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
For a useful comparison on your own drive, match the scan root, access permissions, and size mode. Chart style changes how you explore the results; it does not by itself establish measurement accuracy.
Common questions
When should I choose DaisyDisk?
A good fit for Mac users who want a sunburst, cloud connections, and snapshot tools. One-time license; free trial. Check vendor pricing and direct/App Store edition differences.
When should I choose Disk Graph?
A good fit for people who want saved storage history or a companion on iPhone/iPad. Commercial app; check current developer and App Store purchase options.
Will both apps show the same size?
Not necessarily. Match the scan root, permissions, exclusions, and logical/allocated-size mode. Hard links, APFS clones, snapshots, sparse files, and cloud placeholders can change totals. A reported size is not a guaranteed amount recovered after deletion.
