I'd like to have the My Documents folder on my HP synced with Dropbox, so I have a backup in the cloud. But I can't figure out how to do it without having a copy of My Documents in the My Dropbox folder (i.e., having two copies of My Documents taking up space on my hard drive). I might be overlooking something simple, but the system won't let me move My Documents into the My Dropbox folder, only copy it there. I just want files to upload to Dropbox automatically every time I add them to my computer. Using Window 7 and Windows Explorer, if that helps. Any ideas?
