|---|---|---|
| Best fit | Users interested in the classic treemap or its community successors. | Mac users seeking an analyzer plus duplicate and photo cleanup tools. |
| Visualization | Treemap; features depend on X, Xs, or Y | Sorted folder breakdown and cleanup lists |
| Platforms and requirements | Original X 1.3: macOS 10.13–10.15; Xs/Y requirements differ | macOS 10.13+ (vendor requirements) |

| Open source | Yes | No |
| Native macOS UI | Yes | Yes |
| Cleanup workflow | Check the selected project’s manual; X, Xs, and Y do not share a guaranteed cleanup contract. | Review each module’s action; ordinary cleanup and permanent shredding have different recovery implications. |
| Reports and portability | Check export support in the exact X, Xs, or Y build. Retain its scan records separately; no direct import into NullDisk is documented. | 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. |
Disk Inventory X: what stands out
A good fit for users interested in the classic treemap or its community successors.
Disk Inventory X: strengths
- Treemap visualization of disk usage
- Xs updates the original codebase for Apple Silicon
- Y is a separate Swift/SwiftUI rewrite
Considerations
- The original X, revival Xs, and rewrite Y are different apps
- Compatibility and features depend on the chosen build
- Check each project’s current release and signing instructions
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
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 Inventory X?
A good fit for users interested in the classic treemap or its community successors. Original X is free under the GPL; Xs and Y are independent community projects.
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.
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.
