This plugin (
Disk Usage) shows all files of your WordPress installation at once. These are displayed in a so
called “Sunburst Chart”. Each arc of the chart is either a directory or a file. Move your mouse over an arc to see the size
of the file or directory. The bigger the arc is the bigger is the file/directory.
Very useful to determine the biggest files in your WordPress installation!
Click on an arc to zoom in, and click in the circle to zoom out again.

Does this plugin work on a WordPress Multisite?
Yes since 1.1 it does. Note: For privacy reasons you need to be a Superadmin to use this on a Multisite.
Loading bar doesn’t go away
In this case unfortunately this plugin can’t calculate the sizes of all your WordPress files. Check if there’s a PHP time limit in your WordPress and try to increase it.
