A fast, visual disk-space analyser with an interactive treemap. Scan any folder (or multiple paths), see which files and directories consume the most space, and drill down interactively.
- Treemap – proportional rectangles; larger rect = more disk space used
- Folder composition – directory blocks show an internal colour gradient (left → right) representing the file-type breakdown, with diagonal hatching so they are visually distinct from files
- Interactive zoom – scroll wheel zooms into / out of any selected path
- Click to inspect – left-click a block to see its name, path and size
- Category filter – toggle file categories (audio, video, images, archives, documents, code, …) on the chart
- Right-click context menu – open the item or its parent in the system file manager
- Top-files list – quick list of the 32 largest files found
- Dark mode – togglable light / dark theme, persisted between runs
- Persisted sources – the last scanned path list is restored on startup
Pre-built binaries are available on the releases page.
Alternatively, build from source (requires the Rust stable toolchain):
cargo build --release
# binary: target/release/space_finder- Click Show next to Scan Sources to add folders or files.
- Click Start – the chart renders automatically when the scan finishes.
- Left-click a block to select it; scroll up to zoom in toward the selection, scroll down to zoom out.
- Right-click to open the item or its parent folder in the file manager.
