| Feature | Disk Xray | JDiskReport |
|---|---|---|
| Best fit | Mac users seeking an analyzer plus duplicate and photo cleanup tools. | Users who want cross-platform disk statistics and already use Java. |
| Visualization | Sorted folder breakdown and cleanup lists | Overview statistics charts and detail tables |
| Platforms and requirements | macOS 10.13+ (vendor requirements) | macOS, Windows, Linux (Java) |
| Pricing and editions | Free App Store download; full functionality via subscription or lifetime purchase. The subscription includes a seven-day trial. | No-charge, ad-free freeware; this does not mean open source. |
| Open source | No | No |
| Native macOS UI | Yes | Cross-platform interface |
| Cleanup workflow | Review each module’s action; ordinary cleanup and permanent shredding have different recovery implications. | Use the statistics to guide file review; the cited overview does not specify removal semantics. |
| 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. | Preserve any saved scan files supported by your version and keep important table entries. NullDisk does not import JDiskReport scan files. |
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
JDiskReport: what stands out
A good fit for users who want cross-platform disk statistics and already use Java.
JDiskReport: strengths
- Disk usage statistics in charts and tables
- Runs across Java-capable desktop systems
- Free without ads or expiry
Considerations
- Requires a compatible Java runtime
- Freeware rather than an open-source project
- Check the manual for report storage and file-management actions
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 JDiskReport?
A good fit for users who want cross-platform disk statistics and already use Java. No-charge, ad-free freeware; this does not mean open source.
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.
