Disk Usage Sunburst


This plugin (Tools -> 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.

what an excellent plugin, was having issue with space on server, this immediately identified a rogue plugin that was causing the problem

Our hosts have a max capacity on our account and old files can make some sites get way too big - this plugin is invaluable for tracing the problems.

I'm sort of experienced WP user. But I've forgotten more than I remember, and loathe to use SSH or CLI to actually find stuff. My wp-content folder was waaay tooooo large and I knew something wasn't right but didn't know where to look. After poking around the usual suspects I added Disk Usage Sunburst ... which told me my wp-admin was 3.7 GB... hey that ain't right... poke around... find a 3.5 GB error log.... oops... thanks

Helped me find those elusive huge backup files that were hiding.
