I was told that I need to clear my account because I have exceeded my quota. When I go to my "Shared by you" files, I have stuff from 2014 in there. However, if I try to delete, it appears that I have to do it one file at a time, and then it goes back to the top of the list and I have to scroll all the way down again. There has to be a way to delete old files in bulk rather than one at a time.
