Nijia

Nijia is a native macOS app for understanding what uses your storage and deciding what to keep. Explore disk and folder usage, inspect developer workspaces and worktrees, and organize files with a proposal you can review and edit before acting. For cleanup, Nijia explains why files may be rebuildable and which workspace may depend on them. You choose the scope, review individual selections, and confirm moves to Trash. Scans and review do not automatically delete files. Nijia also includes AI Desk Tidy for proposing file organization. It is a paid Mac app with a 7-day trial and no payment card required.
