An information processing apparatus includes a music file storage unit and a transport processor. The music file storage unit stores a music file, PC-use additional information that can be displayed by a personal computer, and PD-use additional information that can be displayed by a portable device as they are. At the time of move-out, the transport processor copies, to the portable device, the music file, the PC-use additional information, and the PD-use additional information that are stored in the music file storage unit. When the data is correctly written in the portable device, the transport processor deletes, from the music file storage unit, the music file, the PC-use additional information, and the PD-use additional information.
