I am trying to move the dropbox location/folder onto a new external drive (from an internal hard drive). It has been stuck on 3790/68455 files for 3 hours. There is no file so big that it would take this long, so I'm trying to figure out why it's frozen/stuck. And depending on the answer, if I try to cancel and/or restart, what happens to the files that started moving and/or what are the implications if I force a close and start over?
