So, if I permit Dropbox to backup my files (onto a portable HD), which somewhere along the way my new Dropbox said I could do (so I clicked on it before loading up my photos on Dropbox) --then could I simply delete the photos from my Dropbox and they'd stay on the portable HD, but be gone from the Dropbox?? It seems like a cumbersome way to do this, but apparently the backup is storing stuff on my portable HD, so it's kind of like moving a copy there to keep???
Thanks
