What Radix is
Radix is a free macOS application for examining storage usage in files and folders. It scans local and external drives, showing results in sunburst and treemap views, with live progress for scans covering millions of files. Users can compare scans to see what grew, shrank, appeared, or disappeared. Files and folders can be reviewed in a Discard Pile before moving to the Trash. Search, custom scan exclusions, Quick Look, Open, Reveal in Finder, Copy Path, and Move to Trash actions are included. Completed scans can be exported and reopened as read-only snapshots. The maker says scans and saved results remain local, and no account is required. Some folders may need Full Disk Access; Radix identifies skipped files and guides users to System Settings. The app does not show application sizes. It requires macOS 14 or later, is free forever, and is available under the MIT License.
