A method may be performed in a data storage device while the data storage device is operatively coupled to a host device that is registered at a network server as a designated recipient of access requests directed to the data storage device. The data storage device includes a controller and a memory storing one or more files. The method includes receiving an access request originating from a second device that is distinct from the host device. The host device is accessible to the second device via the network server. The method also includes, when the second device is authorized to access the data storage device, sending a response with access information to the second device via the network server.
