SoftwareUtilities
GrandPerspective is a free, open-source disk usage app that draws a folder or drive as a treemap, where each file is a rectangle sized by the space it uses. It makes large and forgotten files easy to spot.
Key Features:
- Colors files by folder, extension, type, size, or age.
- Filters, searches, and navigates folders with the mouse or keyboard.
- Reveals files in Finder, previews them with Quick Look, and deletes them from the view.
- Analyzes Time Machine backups and cloud storage files.
- Saves and exports scan results as an image or text.
Version 3.8.1 requires macOS 14 or later on Apple silicon or Intel. It is free from SourceForge or Homebrew, and $2.99 on the Mac App Store to support development.
