PROBLEM TO BE SOLVED: To transfer a large capacity file between communication terminals without waiting for completion of file transfer at the site, even when the communication terminals are outside a service area.SOLUTION: A file transfer system causes at least one of a first terminal identifier for identifying a transfer source communication terminal and a second terminal identifier for identifying a transfer destination communication terminal, and a file identifier for a file to be transferred to be shared between the transfer source communication terminal and the transfer destination communication terminal using proximity communication in a proximity position in which the proximity communication is possible, and causes the transfer source communication terminal identified by the first terminal identifier to transfer the file identified by the file identifier to the transfer destination communication terminal identified by the second terminal identifier through a server, in different places to which the transfer source communication terminal and the transfer destination communication terminal separately moved after completion of the proximity communication.
