SpaceMan is a treemap disk usage analyzer: In search of lost space (a.k.a. wata-analyzer).
Click the button on the left of the title bar, and choose a directory to scan. You can also provide a directory to scan as a command line argument.
This is free and open source software.
Key Features
- Fast scan and display, with the power of Rust, and gtk4 GPU rendering capabilities.
- Uses the jwalk library as dua-cli does, enabling multi-threaded scans.
- Live display of scan results, no need to wait for the scan to complete.
- Linux-first, but cross-platform. Besides Linux, it runs under macOS and Windows.
