diskonaut

The tool scans a given directory path, loading file metadata into memory while the scan proceeds, allowing immediate exploration of the filesystem. It presents a visual treemap that shows how much space each subfolder and file occupies, and updates the view as the scan completes. Users can navigate through the hierarchy, delete files or folders, and see the amount of space reclaimed during the session.

It is a command‑line utility that runs on Linux, macOS, and Windows, and can be installed via prebuilt binaries, Cargo, or package managers such as DNF, AUR, Homebrew, Nix, and FreshPorts. The program operates entirely in the terminal, offering an interactive interface without requiring a graphical desktop environment.

The software targets users who need to understand and manage disk usage on local machines, especially those comfortable with command‑line workflows. Its distinctive feature is the real‑time treemap visualization combined with in‑session deletion tracking, providing immediate feedback on space recovery.
