Right-Click to Analyze instantly
TreeSize integrates deeply into the macOS Finder. Analyze any directory in a split second without even opening the app first:
- Quick Action Service: Right-click any folder, go to Quick Actions (or Services), and choose Analyze with TreeSize to boot and scan immediately.
- Open With Menu: Right-click any directory, choose Open With, and select TreeSize to audit its size in a click.
- Finder Drag & Drop: Drag any folder directly from the Finder and drop it anywhere inside the TreeSize window to instantly re-focus the scan.
Launch from your Terminal
Integrate TreeSize perfectly into your development workflow. Type a single command followed by any folder path to launch the visualizer immediately.
During local installation, a symlink is automatically generated in /usr/local/bin/treesize to provide instant command-line utility.
