Baobab − A graphical tool to analyze disk usage

baobab  [directory]

baobab is able to scan either specific folders (local and remote) or devices, in
order to give the user a tree representation including each directory size or
percentage in the branch. It also auto‐detects any mounted/unmounted device. A
graphical representation is also provided for any selected folder.
