NullDisk passar om …
- A radial sunburst map instead of lists or treemaps — see usage at a glance and drill in with a click.
- A staged removal collector: queue suspects, review, then Trash everything together.
- Allocated-size measurement with hard-link dedup, so reclaimed space matches reality.
Pros & cons

- Community revival builds run natively on Apple Silicon
－ Svagheter
- Interface shows its age despite the revival builds
- No collector tray, previews, or modern sandbox handling
- Fork landscape (X vs Xs vs Y) can confuse new users
Vanliga frågor
What is the best alternative to Disk Inventory X for Mac?
For most Mac users it's NullDisk: native SwiftUI, a radial sunburst map, a staged removal collector, and zero data collection. Disk Inventory X users who want treemap views and open source pricing will feel at home within minutes.
Is there a free alternative to Disk Inventory X?
Yes — GrandPerspective and Disk Inventory X are free and open source with genuine treemap analysis. They lack NullDisk's collector workflow and sunburst map, but they find the biggest hogs fast.
How do I switch from Disk Inventory X to NullDisk?
Note the largest folders Disk Inventory X flagged, then run the same scan in NullDisk and rebuild the cleanup in its removal collector. The full walkthrough is on our switching guide.
Kort sagt
Disk Inventory X is a fine free tool for treemap fans on macOS. But if you want the whole job — see, stage, and safely remove — done natively on a modern Mac, NullDisk is the upgrade. Bytarguide →
