MATE Disk Usage Analyzer

As its name implies, Disk Usage Analyzer is a graphical utility that you

can use to view and monitor your disk usage and folder structure. It displays

summary information in ring or treemap charts.

You can perform scans on a file system, your home or any other folder - local

or remote. There is also an option to constantly monitor any external changes

to the home directory and warn the user if a file is added/removed.
