By the installation of BTSync on Windows 7, i choose the folder btsync from the NAS. When i launch BitTorrent Sync 1.3.106 in Windows 7 and +Add folder, in Folder secret, i use the one from de folder in the NAS. When i browse to "Folder to sync", i direct to the folder "archief" in Explorer. By clicking OK, i have the message: Selected folder is already added to BitTorrent Sync. What do i wrong?
