| Cleanup workflow | No automatic deletion after scanning; most tools use Trash by default. Secure Remove and Trash emptying are permanent. | Delete files or folders from the view; review selection and deletion preferences. |
| Reports and portability | The cited pages do not establish scan-report export. Keep any important history or paths before rescanning; retain the original files until decisions are verified. | Save the scan for reopening in GrandPerspective, or export text and images. NullDisk does not import GrandPerspective scan files; retain exports and rescan the same location. |
diCleaner: what stands out
A good fit for Mac users seeking free storage analysis alongside broader maintenance tools.
diCleaner: strengths
- Storage analysis, large/old files, and duplicate/similar-photo tools
- App uninstallation, leftovers, and startup-item review
- Selection-based cleanup with Trash defaults for most tools
Considerations
- Permanent removal and privacy tools have different effects from Trash
- App Store privacy disclosure lists some non-linked data
- Cleanup eligibility depends on files, apps, and permissions
GrandPerspective: what stands out
A good fit for people who want a free, inspectable treemap and reusable scan records.
GrandPerspective: 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
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 diCleaner?
A good fit for Mac users seeking free storage analysis alongside broader maintenance tools. Vendor says free to use with all current features included.
When should I choose GrandPerspective?
A good fit for people who want a free, inspectable treemap and reusable scan records. Free from SourceForge; the same app is $2.99 in the US App Store.
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.
