Disk Usage Analyzer
Disk Usage Analyzer helps Linux users see how much storage is occupied and how much remains.
What Disk Usage Analyzer is
Disk Usage Analyzer helps Linux users see how much storage is occupied and how much remains. It scans chosen folders, storage devices, external drives, and online accounts, then presents folder sizes in a tree view and a graphical representation. The app focuses on files and folders; application sizes and file-type breakdowns are not provided. The GNOME app page directs users to Flathub for the latest version, 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 assigns it a “Medium Risk” label, and the app page does not state security certifications or compliance details. Disk Usage Analyzer is free; the listed Free plan is free.
