Abstract
A file transfer method and a file transfer system are provided for making it possible to minimize aggregate waiting time of the whole users for data transfer using a multicast protocol. In the file transfer method of transferring a plurality of program files from a recorder storing a plurality of program files via a network to a plurality of mobile terminals using a multicast protocol, the recorder determines order of transfers of the plurality of program files for the purpose of transferring the plurality of program files in order of digital data files, which is the ascending order of file size of the plurality of program files (step S), the recorder transfers the plurality of program files on the basis of the order of transfers (steps S-S), and the plurality of mobile terminals selectively receives the plurality of program files (steps S-S), thereby reducing aggregate waiting time that is a sum total of transfer time of the whole users.
