This File Transfer Time Calculator is used to determine the approximate time that a file would take to transfer over a particular interface . The speeds are optimistic because the actual inferface will be slowed down by overhead (ex: requests for the information, syncs, ...), more than one transfer at a time, and the interface not performing at the standard speed.
