I encrypted a few folders in my account directory and decided that since I usually tug around a majority of those files with me, it might not be the best idea to encrypt them so I decided to unencrypt them. Well I get to a folder that says it can't be unencrypted because it's in use by another process. Now I've shut the computer down, restarted in safe mode, killed procs, and I still can't get the thing to unencrypt. Any advice?
