Common questions

When should I choose Nektony Disk Space Analyzer?

A good fit for Mac users who want a sunburst and integrated file-management actions. Free download; verify the selected store edition and its in-app purchase terms.

When should I choose Space Radar?

A good fit for developers exploring alternative visualizations and an inspectable codebase. Free under the MIT license; check repository build/release instructions.

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.
