Overview

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.

Excellent plugin!

by Elchanan Levavi·7 months ago

Installation was quick, and within a minute I could clearly see which folders were taking up the most space. The sunburst chart is intuitive and easy to understand, and it helped me solve a disk space issue without digging through FTP or SSH. Exactly what I needed.

Brilliant Visual Diskspace Breakdown

by Alex T·1 year ago

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.

Amazing – does what it should

by Christian Strasser·2 years ago

This plugin helped me find some file oaks that made my website slow and the server memory extremely full (database cache log files).

Thank you!

If you don’t use this? You’re not a WP Dev

by WPsinceO3·3 years ago

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!
