Beautiful and Helpful

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

Amazing Straightforward Plugin

By angelapeden on March 14, 2025

No ads, no fluff, just does what it says. One click and it will scan your site to show you what files are taking up the most space.

I couldn't for the life of me figure out what files were taking up so much space on a client site until I ran this plugin. It found a super old backup file from a backup plugin that was never deleted totaling over 7GB of disk space.

Understand that it will not delete the files for you. You will still have to manually delete them on your own, but it will pinpoint what the files are and where they're located so you don't have to manually go through every single file and folder on your sever.

Very useful plugin

My WordPress site was getting close to storage allowance, this plugin helped me quickly find folders and files that were taking up a lot of disk space. Removed the files and I'm now back within my allowance.

Thanks for a great plugin
