About Disk Usage Analyzer

Disk Usage Analyzer, also known as Baobab, scans folders, storage devices and online accounts and shows the size of each folder both as a tree and as a graphical chart, so it is easy to see where space has gone.

It is part of the GNOME app set, installed through Flathub or a Linux distribution's packages, and is maintained by GNOME contributors. Version 50.0 was released in March 2026.

Strengths

  • Tree and chart views of folder sizes
  • Scans folders, whole devices and online accounts
  • Integrates cleanly with the GNOME desktop
  • Actively maintained with regular releases

Limitations

  • Linux only
  • Shows usage but has few cleanup features of its own
