I just setup btsync 1.2.72 on my freenas 9.2.1 box at home. i also setup the client at my computer at work. I chose a folder with all of my documents as the folder i want to sync. will btsync sync existing files or will it sync only what i add to the synced folder from now on? and if it will only sync from now on, how can i get it to sync what i have on my work computer?
