Works very well

This plugin works - plain and simple.

I was recommended another plugin but I kept getting critical errors, it never compelted a full scan.

This worked first time. I got some red screens with errors but they were Cloudflare errors not website errors.

I managed to locate 4GB of log files and other junk to clear.

Thanks for the great and very useful plugin.

Does what it says on the tin

Found 28 gigs of unneeded image backup files! Saved me costly hosting upgrades

By skyzlmt on January 26, 2026

Website with a lot of images and when I went to create a staging copy of my site to do so updates, I was surprised my site had exploded in size... and I didnt have enough remaining space left in my hosting plan. I was contemplating an expensive hosting upgrade to get more storage space.

With a Disk Usage Insights scan it found TWO 13gb files that I had forgotten where there... well i didnt really know? I am also switching to a new webp/avif creator and several months prior had discovered I was creating TONS of unnecessary file sizes and I ran a tool to wipe them out... not realizing it created 26gb of zip files of the deleted images. BOOM... there was my 26gb explosion in file size. in regards to my needed staging site copy it was really 56gb of data lost.

Worth every penny... which I paid nothing! Looking for a donate option.

it's good

Well made, I appreciate adding that donut chart / file browser.

Beautiful and Helpful

By kiyasu on December 13, 2025

I downloaded this plugin months ago and thought it was helpful. But recently I checked and found out this plugin changed. It now has an even better interface that is beautiful and much easier to view. Wow, I really like how this plugin looks now. Months ago it was okay but very useful, and probably I was grateful for it. But now I find myself enjoying how beautiful the new data interface is and so glad I have this plugin in times of need. I also like how now I am able to directly browse some folders on the page with folder size. Amazing plugin. I think this plugin is pretty much perfect now. Helped me so much in times of need and very easy to use. I recommend using both WordPress backend and FTP alongside this plugin. (EDIT: To further clarify, here's an example. Deleting files directly from the Media page via WordPress backend may not delete all related files, so I like to directly check via FTP for more efficient work.)

Muito bom
