Permanently deleting files without selecting them by hand

Hi all,

My Cloud is full, so i decided to delete some files.

I know that they will end up in the deleted files folder in https://assets.adobe.com/deleted. And they will only really be gone if you remove them there. Which is a good feature in my opinion. It prevents us from accidentally removing files, and in case of an emergency you're able to get back to an older verdion of your project file.

However, as an animator i work with image sequences and folder that concist of a lot of files.

Is there really no other way then to mark every file and delete it? I've selected multiple files at once, but the site is to slow to delete a lot of them. It simply crashes.

I really don't understand how there is no option to clean the entire folder. It will costs me multiple hours to get rid of all the files by hand, since selecting more than 10 files at the same time will crash the site.

Am i missing something or is this just incredibly bad UI design by Adobe? How do other people deal with this?
