Abstract

According to one embodiment, there is provided a memory system including a proximity wireless interface, a memory, and a controller. The proximity wireless interface can communicate with a correspondent device. In the memory, a file having an extension is stored. The controller specifies, if device information related to an attribution of the correspondent device is received in the proximity wireless interface from the correspondent device, at least one of an extension recognizable in the correspondent device and an extension unrecognizable therein based on the device information and that performs first transmission control according to a specified result. The first transmission control includes at least one of selectively transmitting a file having the recognizable extension from the proximity wireless interface to the correspondent device and not transmitting a file having the unrecognizable extension from the proximity wireless interface to the correspondent device.
