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.

I moved my websites over to Direct Admin (DA) panels. DA doesnÌtumọ̀ Yorùbá: ’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.

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!

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 youÌtumọ̀ Yorùbá: ’re here like me downloading DUS for a build. 5 stars all day, everyday!
