CC Deleted Files folder taking 60GB of storage

I was about to upgrade my plan as I received a warning that my 100GB storage was almost full.  I checked the Deleted Files folder on CC and noticed it was huge (not possible to know the exact size though). 

The amount of files was massive so there was no way to delete them all together. But the worst part was the page freezing or even crashing when I selected too many items to be deleted. So this was incredibly time consuming as I had to delete them manually one page scroll at a time. 

• It would be great if Creative Cloud could be more clear about the size of the cloud trash bin before offering to upgrade your plan. 

• Maybe add a way to automatically delete older files? I had files from 4 years ago!

• And of course a way to delete all the files together would be necessary.
