| Cleanup workflow | Collector stages items, then permanently removes them after confirmation and a cancellation countdown. It does not use macOS Trash. | Stage items in the Collector, then send the reviewed batch to Trash. |
| 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. | The developer documents exporting maps as posters with Command-Shift-E. Keep that image as a reference; it is not a scan file that NullDisk can import. |
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
Delve: what stands out
A good fit for Apple Silicon users on macOS 26+ who want two maps and staged cleanup.
Delve: strengths
- Treemap, sunburst, and file list
- Logical and on-disk measurement with filtering
- Quick Look, collector-to-Trash, and map image export
Considerations
- Requires macOS 26 or later
- Apple Silicon only in the current requirements
- A map export is a visual record, not a file backup
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 Delve?
A good fit for Apple Silicon users on macOS 26+ who want two maps and staged cleanup. Vendor lists $4.99 once after a 14-day trial.
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.
