I use Premiere Pro and After Effects pretty frequently, so I'm often dealing with large videos. I had reached my 100 GB placing files into a folder I created there and I started deleting videos I didn't use in the current projects by highlighting and hitting delete. I then noticed I was still getting constantly notified (after each frame render) that I was full on storage still despite only having 60-ish GB when I preview my Creative Cloud Folder. When I check the Creative Cloud app, however, it still displays me as using 100 GB. Some support articles said it could have to do with my cache, but I deleted it on both apps fully and still can't use the programs. Thanks in advance.
Unfortunately, I had to manually delete 2000+ frames and video files from the "Deleted" tab on the CC website that showed blank on the CC app. The page also only let me do it 150 files at a time because the website ground to a halt otherwise. Either way, though, thanks for the help!
