SpacePeek

A read-only Quick Look inspector for folders and archives.

+ SpacePeek: Punti di forza

  • Read-only by design — it cannot delete anything, so it's extra safe
  • Peeks inside folders and archives with Finder-style Quick Look
  • Very cheap Pro unlock

- SpacePeek: Debolezze

  • Read-only means no cleanup workflow at all
  • No sunburst or treemap overview of a whole drive
  • Niche tool, not a full disk analyzer
