Report Two Way Syncing Between Mobile And Pc? in Sync General Discussion Posted November 21, 2014 Oh man... this is cool! I realized I was selecting the "New backup" option for my folders. What I needed to do was create an empty folder on on the PC and then "Add Folder" on mobile device. Still have a question on the Archiving. Is it true for any type of syncing with BitTorrentSync that only file changes are recorded in the Archiving folder and not file deletion?
