SENDING FILES FROM ONE DEVICE TO ANOTHER DEVICE OVER A NETWORK

PURPOSE: Transmitting files from a device to another device through a network is provided to enable destination devices to obtain a copy of a file from a source device during a period when an intermediary cannot use. CONSTITUTION: Data relating devices is stored. The devices include a first device and destination devices. A transmission notification indicating a file stored in the first device to other devices is received from the first device through a network(310). The file is stored in a remote permanent storage(320). The file is transmitted to the device. The file does not permit the access of a device regardless of the file reception of a random destination device depending on the elapse of a specific time.
