As you recall, the admin is not God so you may have to add your admin account to the owner of this folder. There are many articles about that so I'll stop here.

I have folders named like "11a9591c2490188bbd3b" . I could not delete them as the deletion demands admin rights. But I am the admin of my system. What can I do to delete them?
Thanks
