Disk Usage Sunburst

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.

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.

I moved my websites over to Direct Admin (DA) panels. DA doesn’t include the option to see file diskspace breakdown like cPanel offers. No problem, because this plugin is far better! And I found some other little gremlins in the mix. I can confirm it works with WP 6.5.2 (most recent at the time of this review). Will be recommending this to my clients.

I hardly write reviews anymore. Why? Because everything is pure poop and clickbait for premium „features“ but every once in a while I come to download one of my must haves for a client site and I have to write something because of how dependable the plugin is and how it is literally a necessity for a site and that is why DUS is getting a 5 star. No one, has tried to do what they have done and it is such a addon to a devs toolbox. Everyone else is competing for social feed plugin users or the coolest new Elementor widgets and yet if you know anything about WP you’re here like me downloading DUS for a build. 5 stars all day, everyday!
