• determining a mode of the file transmission/reception device as any one mode of a master mode or a slave mode when being reconnected to the first device;
• switching the file transmission/reception device to any one mode of the master mode or the slave mode after being reconnected to the first device;
• performing transmission, reception, or transmission/reception of a file between the first device and the file transmission/reception device in the master mode or the slave mode in accordance with the determined mode,
• wherein
• when a connection between the first device and the file transmission/reception device is established, sending the transmission condition information of the host device in the transmission condition information managing unit to the first device upon a request from the first device, and
