Disk Xray: strengths
- Size-sorted folder scanner
- Byte-by-byte duplicate checks and similar-picture search

Considerations

- Shredder operations are permanent
- Vendor limits content overwriting to supported HDDs, excluding SSD/APFS/network drives

LumaDisk: strengths
- Sunburst and treemap with live scan updates
- Build-cache radar, duplicate groups, and unused-file lists
- OneDrive/Dropbox connections; iCloud through its local folder
Considerations
- Verify Mac CPU support; current site highlights Apple Silicon
- Features beyond scanning require an unlock after trial

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 LumaDisk?
A good fit for Mac/Windows users wanting maps, duplicates, and build-cache discovery. Seven-day full trial; scanning stays free. Vendor lists $6.89 once for the remaining features.
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.
