I have BTSYNC installed on a raspberry pi with a 3T usb drive. I synced a large number of files via a "one way folder" to the hard drive, shut down the pi and connected the drive to another machine. I didn't change any of the files, but they may have had their timestamp changed (I didn't think the check). When I hooked up the drive to the Pi, turned on the Pi and restarted BTsync, it started to resync the entire drive. How does the app determine if the file needs to be resynced? Would it do this behavior every time I turn off the PI?
