A file transfer system is provided in which the image data photographed at a destination place by the user is easily transferred to a specific file server. Specifically, a memory card reader is controlled by a system controller. A memory card is a recording medium for saving an image data file. A modem has a function of implementing the external communications with the memory card reader employing a telephone line. In a specific recording area of the recording medium, the positional information indicating the position of any specific region on file servers is recorded, and when the recording medium is mounted on the memory card reader, the memory card reader reads the positional information and the file, and the file is transferred to the specific region on the file servers indicated by the positional information.
