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
OmniDiskSweeper: what stands out
A good fit for Mac users who prefer a free size-sorted browser to a chart.
OmniDiskSweeper: strengths
- Largest-first file and folder browsing
- Open items or move them to Trash
- Official downloads include versions for older Macs
Considerations
- Column browsing rather than a graphical disk map
- Check the download requirements for your macOS version
- The cited overview does not document saved reports or duplicate matching
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 OmniDiskSweeper?
A good fit for Mac users who prefer a free size-sorted browser to a chart. Free download from The Omni Group.
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.
