I started dropbox on new computer. I don't want to sync anything but the file or files I am sharing. Somehow I turned on backups and it started syncing everything on the computer. So I found out how to turn off the backups in the preferences, did that, so that now under backups in preferences it only says set up.....nevertheless the dropbox still seems to want to sync everything....I paused syncing in the dropbox dropdown menu and every time I try to resume syncing it says it is syncing 371 files......I just want to sync and share 1 file, how do I get it to stop? !!!
