My wife and I don't trust the cloud anymore and found several recommendations for Bit Torrent Sync. We have 6 Macs (iMac, 2 iPads, MacBook, & 2 iPhones). We want to sync important files on these Macs without using the "Cloud". I downloaded Bit Torrent Sync for my ipad but I'm stuck now. I want to create a folder to hold 2 very important files. When I click on "Add Folder" it asks me for a key while my ipad camera is scanning the room. Can someone talk me thru the process?
