よくある質問
What is the best alternative to DeepClean for Mac?
For most Mac users it's NullDisk: native SwiftUI, a radial sunburst map, a staged removal collector, and zero data collection. DeepClean users who want list views and paid pricing will feel at home within minutes.
Is there a free alternative to DeepClean?
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 DeepClean to NullDisk?
Note the largest folders DeepClean flagged, then run the same scan in NullDisk and rebuild the cleanup in its removal collector. The full walkthrough is on our switching guide.
まとめ
DeepClean is a capable tool for list 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. 移行ガイド →
