PURPOSE:To perform the transfer of data with highly effective use of the resources by integrating a transmission status file SF with a reception SF, monitoring the idle capacity of the integrated SF after a fixed time for deletion of the undesired data, and compressing the SF. CONSTITUTION:A store means 2 transfers the desired data on a user file 1 and its attribute information to a data file 3 and an SF 4 to store them there. The transfer condition of the data transfer destination is stored in a transfer condition information storing means of SF4. A message transmission means 7 reads the information out of the SF 4 every fixed time and compresses the SF 4 when an idle area of the SF 4 is decuded down to a level less than a fixed size. At the data transfer destination (computer), a reception file 9 is secured after reception of a message from the means 7, the transfer information is written into the SF 4, and then the information is read out of the SF 4 and sent to the transfer destination. The transfer destination message reception means 8 updates the transfer condition storing area of NF. Each file transmission means 6 reads the SF 4 every fixed time and sends the file 3 to the transfer destination. This operation is repeated until no transfer data is received from each transfer original yet.
