Disk Usage Sunburst

By RAIDBOXES.io

Description

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.

FAQ

Where is it?

After activation you find the tool under Tools -> Disk Usage

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.

Hugely useful

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.

yes, and thank you

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

Super useful

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

The alternative to P3 plugin

December 5, 2019
I used to use the P3 plugin to compare the sizes of my plugins, which was an important tool, but the author of the plugin stopped updating it. I came across this plugin from an article reviewing 16 alternatives to the P3 plugin. The disk usage sunburst was listed at the bottom. But it really is the only real alternative. When you turn it on and drill down to where the wp content>plugins area is, you can see which of your plugins are big (e.g.: All-in-one Calendar, WP SEO Yoast, GravityForms) and which ones are not (e.g.: Disk Usage Sunburst).
