| Cleanup workflow | Review each module’s action; ordinary cleanup and permanent shredding have different recovery implications. | Pro moves selected files and app leftovers to Trash after review. |
| Reports and portability | The cited product page does not document scan export. Keep duplicate decisions and paths separately; hard-link accounting in NullDisk is not duplicate-content detection. | The overview does not establish scan-report export. Preserve any app-removal decisions and rescan the same folders in NullDisk. |
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
DissectMac: what stands out
A good fit for people who want free inspection and optional paid app/leftover cleanup.
DissectMac: strengths
- Free map, file search, and live monitor
- Filters for developer files and large storage categories
- Pro uninstaller and app-leftover cleanup
Considerations
- In-app clearing and uninstallation require Pro
- Treemap is the documented graphical view
- Confirm suspected leftovers belong to apps you no longer need
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 DissectMac?
A good fit for people who want free inspection and optional paid app/leftover cleanup. Map, search, and monitor are free; Pro is listed at $12.99 once plus tax.
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.
