## 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.

## Installation

 1. Upload `disk-usage-sunburst.zip` to the `/wp-content/plugins/` directory
 2. WordPressහි ඇති ‘ප්ලගින’ මෙනුව හරහා ප්ලගිනය සක්‍රිය කරන්න

## 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.

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 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.

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