MacDirStat scans any folder and turns your filesystem into a beautiful, interactive visualization. Find duplicates, delete what you don't need, reclaim your space.
Features
Every file and folder visualized as an arc sized by disk usage. Depth rings show hierarchy at a glance.
Finds identical files by content hash and shows exactly how much space they waste. Delete all copies in one click.
See which file types are eating your space — videos, code, archives, images — color-coded and searchable.
Click any folder to zoom in. Click back to go up. Navigate your disk like a map.
Right-click any file or arc to move it to Trash. The chart updates instantly — no need to open Finder.
Feel the weight of files through your trackpad. Large files give stronger feedback. A detail that matters.
