DiskPilot is a fast, native-feeling disk space analyzer for:
- macOS (Intel + Apple Silicon)
- Windows x64
- Linux (AppImage + .deb)
It scans any directory, calculates real file sizes (with hardlink deduplication), and visualizes storage usage through a powerful tree view and treemap.
No cloud. No tracking. No subscriptions. Just a fast, free storage analysis tool.
Most operating systems show abstract storage bars — but don’t tell you exactly where your space is going.
DiskPilot gives you:
- Precise folder-level disk usage
- Visual treemap for instant space hog detection
- Accurate size calculation (no double-counting hardlinks)
- High performance even with millions of files
- Native experience across Windows, macOS, and Linux
- Deep disk scan — recursively walks any folder in seconds
- Hardlink deduplication — accurate real disk usage calculation
- Tree view — sortable columns: Size, Allocated, Files, Folders, Last Modified
- Virtual scrolling — handles millions of rows without lag
- Treemap view — squarified treemap layout
- Click to drill down
- Breadcrumb navigation
- Multi-selection: Click, Shift+Click, Ctrl/Cmd+Click, Shift+Arrow
- Bulk delete
- Delete to Trash — safe removal via system Trash
- Column resizing — widths persist across sessions
- Live scan rate (GB/s) + elapsed time
- Dark / Light / Auto theme
- Keyboard-first navigation
- Native context menu: Open, Show in Finder/Explorer, Copy Path, Delete
- Cross-platform builds: macOS Universal (.dmg), Windows NSIS installer, Linux AppImage + .deb
