Disk Usage Analyzer vs DiskScope

Disk Usage Analyzer is a free Linux desktop app for checking how storage is used and how much space remains. It scans selected folders, storage devices, and online accounts; external drive scans are also supported. Results present folder sizes in a tree view and a graphical representation, so users can inspect how a scan’s contents are distributed. The app page directs users to install the latest version from Flathub, which lists aarch64 and x86_64 architectures. The GNOME app page lists version 50.0, released on 2026-03-13, and names Paolo Borelli, Stefano Facchini, and Christopher Davis as maintainers. Users can report issues or suggest ideas through the app’s issue tracker. Flathub labels the app “Medium Risk.” The plan is listed at free. The app page does not identify which online account services can be scanned, and it does not state security certifications or compliance details.

DiskScope is a free, open-source desktop app for analyzing disk usage, finding files, and uninstalling applications. It scans files, folders, and apps in parallel, showing results in a sortable table, tree explorer, and zoomable treemap. Views include application sizes and file-type breakdowns. Fuzzy search filters by type, extension, size, and modified date and is designed to remain smooth beyond 100,000 rows. DiskScope reports actual on-disk usage, including sparse and compressed files. Deleted items move to the Recycle Bin; emptying it permanently clears contents after confirmation. On Windows, the Applications tab shows an installed program’s command before launching its native uninstaller. Disk analysis and search work on Windows, Linux, and macOS. Downloads list Windows 10/11 x64, macOS 12 or later, and Linux x64 builds. The macOS and Linux builds are marked experimental and not tested yet. The app runs locally with no telemetry, according to its maker, and checks for signed updates.
