Disk Xray: what stands out
A good fit for Mac users seeking an analyzer plus duplicate and photo cleanup tools.
Disk Xray: strengths
- Size-sorted folder scanner
- Byte-by-byte duplicate checks and similar-picture search
- App uninstaller, disk cleaner, and optional file shredder
Considerations
- Six modules serve different cleanup tasks
- Shredder operations are permanent
- Vendor limits content overwriting to supported HDDs, excluding SSD/APFS/network drives
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 Disk Xray?
A good fit for Mac users seeking an analyzer plus duplicate and photo cleanup tools. Free App Store download; full functionality via subscription or lifetime purchase. The subscription includes a seven-day trial.
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.
