Patent attributes
A read-only-memory (ROM) medium in which a file constituting application software and an additional content file are recorded is mounted to a media drive. A recording processing section copies the file recorded in the ROM medium to an auxiliary storage device. After copying the additional content file to the auxiliary storage device, the recording processing section copies the file constituting the application software to the auxiliary storage device. In the case where the additional content file downloaded from a content server is stored in the auxiliary storage device, the application software can utilize both the additional content file copied from the ROM medium to the auxiliary storage device and the additional content file downloaded from the content server into the auxiliary storage device.
