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](https://wordpress.org/support/topic/brilliant-visual-diskspace-breakdown/)󠁿

 [Alex T](https://profiles.wordpress.org/trecartin/) 16. April 2024

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.

 [Christian Strasser](https://profiles.wordpress.org/cswebdesigns/) 1. Oktober 2023

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](https://wordpress.org/support/topic/if-you-dont-use-this-youre-not-a-wp-dev/)󠁿

 [WPsinceO3](https://profiles.wordpress.org/mbedev/) 6. September 2022

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!
