Please add a little more information to this dialog, as it is completely non-intuitive what the 'correct' answer for this is. I had to figure it out by searching the web. Perhaps something like this: The destination folder you specified 'full path to folder' seems to belong to a previous installation of BitTorrent Sync. If this is the case, and you would like to transfer ownership of the folder to this version of BitTorrent Sync, choose the "reset ownership" button below. If you would like to leave the folder alone, then choose the "Cancel" button below and choose a different folder to sync. <Reset Ownership> <Cancel> ps - the book "About Face" has a great chapter on designing usable dialogs.
