In their own words
Disk Usage Analyzer
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.
