PURPOSE:To eliminate the need for the preparation of another communication means obtaining the transmission/reception timing of file transfer by allowing a request side application program to read out a control information file from the requested side of file transfer prior to the file transfer, thereby knowing the current file transfer state and selecting and transferring only the file having effective information. CONSTITUTION:The file transfer requesting side application program 1 reads out a control information file 5 defined with the file transfer requested side application program 2 prior to file transfer. When a file A to be transmitted is present on the side of the program 1, a transmittable file included in a control information file 5 in the program 2 is retrieved and transferred. When the information to be transferred is present on the file 5 on the program 2, the file information is received by the transfer of the file 5. Consequently, it is unnecessary to prepare another communication means for obtaining the transmission/reception timing of file transfer.
