DiskScope is a disk-usage analyzer for the GNOME desktop on Linux. You point it at a folder and it shows you exactly what is taking up space, organized by category, with heat-colored bars that make the biggest offenders easy to spot at a glance. When you open it, the main screen shows a ring diagram of your disk's used and free space, a breakdown by file type (Videos, Audio, Images, Documents, Archives, Code, Applications, and Other), and the size each category takes. From there you can tap a category to see its largest files, or switch to a folder browser that lets you drill into any directory. Each folder in the tree shows a color-coded bar, its size, and what percentage it represents of its parent folder. A dedicated free-up-space view lists things that are safe to clear without losing important work: your Trash, per-app caches, and build directories from coding projects like node_modules or Rust's target folder. Before you delete anything, DiskScope shows a risk badge and a plain-English sentence explaining what would happen. A browser cache is labeled safe to remove, while an unrecognized folder is flagged as something to check first. Clearing defaults to moving items to the Trash so you can undo a mistake, a switch lets you delete permanently to reclaim space immediately. The app is built in Rust with the GTK4 and libadwaita libraries and follows GNOME design conventions. The scanning engine runs in parallel across CPU cores to handle large directories quickly, and you can cancel a slow scan at any time. It counts hard-linked files only once and never follows symbolic links, so usage numbers are accurate. You can install it from a prebuilt tarball without needing a compiler or developer tools. Building from source requires Rust plus the GTK4 development libraries. The project is currently in alpha.
