An information display apparatus which reproduces images stored in a detachable recording medium acquires file identifying information which identifies a file stored in the recording medium. Also, it determines whether or not specific attribute information about the file identified by the file identifying information exists and acquires attribute information existence information which indicates the presence or absence of the attribute information. Then, the information display apparatus generates an image file list which associates the file identifying information with the attribute information existence information. The information display apparatus acquires, from the recording medium, specific attribute information about files determined to have attribute information by the attribute information existence information among files recorded in the image file list and determines a reproducing method of files stored in the recording medium based on the file identifying information and the attribute information.
