Disk Usage Analyzer
What it is
Disk Usage Analyzer is a free Linux desktop app for checking how storage is used and how much space remains. It can scan selected folders, storage devices and online accounts, including external drives. Results present folder sizes in a tree view and a graphical representation, so users can inspect how space is distributed across a scan. The GNOME app page directs users to install the latest version from Flathub, which lists aarch64 and x86_64 architectures. That 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 app page does not state security certifications or compliance details. Its listed Free plan costs nothing for disk usage scanning on Linux desktop.
