Reorganize local files and restart new iCloud backup
I'm a longtime Mac user but still have trouble fully understanding the way iCloud works - particularly Desktop and Documents. I want to work with all my files locally, and have iCloud as a backup or for non local archiving and sharing. Right now I've got a mess with some files only on iCloud and some downloaded locally and the folders don't match. How can I be sure I have everything on my local drive. so I can reorganize it, then how do I restart iCloud from scratch?
