When a user requests the process of saving files stored in a memory card in a storage medium, such as DVD-RW, in MPV format, the multifunction printer 10 selects a file available for printing based on file extensions from the plurality of files stored in the memory card (step S130), creates a folder, and copies the selected file into the folder (step S140). The multifunction printer subsequently create and save a manifest in the folder, and stores information on saving location as asset information of the selected file in the manifest (step S160). The multifunction printer writes metadata into the asset information (step S170-S210) and registers link information to the created manifest in root manifest (step S220). A file can be readily acquired afterwards by using the root manifest and the manifest and be printed out. And files available for a predetermined usage can be managed easily.
