Can't download my cloud files

Hello. I have downgrade my Adobe subscription so my storage is full. I want to download my cloud files to free up disk space on the cloud but I can't : in my desktop cloud application I have the message "An error has occurred" and if I try in the web application "storage is full". How download my files ?

If I try to mark my file as "available offline" I have again the error "Storage is full" and on my computer the folder is empty

Thanks
