Common questions

When should I choose SpacePeek?

A good fit for Finder users who want to inspect archives before extracting or deleting them. Free previews; optional $3.99 one-time Pro purchase in the US App Store.

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.
