The present invention is to provide a system including at least one storage device for storing at least one file each having a file name, a home gateway having a routing identification code and connected to the storage device, and a server connected to the home gateway via the Internet for receiving the routing identification code and the file name uploaded by the home gateway. The server stores a user's registration information corresponding to the routing identification code. When a terminal device connected to the server via the Internet uses the registration information to pass the server's verification and thus log in the server, the server transmits the file name to the terminal device and, when receiving a request instruction from the terminal device, then retrieves the file from the storage device by way of the home gateway and then sends the file to the terminal device as requested.
