I have run low on space on my internal drive and added an external drive for my Dropbox. I have gone through the process of connecting and syncing my Dropbox account to my new external Dropbox drive. However, it appears that any files I add or remove from my new Dropbox external drive are also being added and removed from my Dropbox folder on my internal system drive. When I look at Dropbox Preferences, I see that the location is set to sync only with my external Dropbox drive. I have restarted my computer and the problem persists. Any suggestions?
