| Cleanup workflow | Review each module’s action; ordinary cleanup and permanent shredding have different recovery implications. | Inspection and copying; use Finder or a separate cleanup tool for removals. |
| 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. | SpacePeek previews existing folders and archives. Keep original archives and important paths; moving to NullDisk does not transfer Quick Look extension features. |
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
SpacePeek: what stands out
A good fit for Finder users who want to inspect archives before extracting or deleting them.
SpacePeek: strengths
- Preview and search folders plus ZIP, 7z, and RAR archives
- Folder-size overview without background indexing
- Pro adds deeper navigation and copying archive members
Considerations
- An inspection companion rather than a full-drive cleanup utility
- Free browsing stops after the first child level
- Pro archive copying is limited to 100 MiB per file
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 SpacePeek?
A good fit for Finder users who want to inspect archives before extracting or deleting them. Free previews; optional $3.99 one-time Pro purchase 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.
