Claim:
An information display apparatus which reproduces an image file stored in a recording medium, comprising: an acquiring unit adapted to acquire a short file name which identifies an image file stored in the recording medium; a setting unit adapted to set an attribute information existence flag which indicates whether or not an extended file name corresponding to the image file identified by the short file name is stored in the recording medium; a generating unit adapted to generate an image file list which records short file name of each of image files stored in the recording medium and records the attribute information existence flag in association with the short file name; and a determining unit adapted to determine a reproducing order of the image files recorded in the image file list by sorting image files recorded in the image file list by using the short file name for a file determined not to have an extended file name by the attribute information existence flag and by using extended file name instead of the short file name for a file determined to have an extended file name by the attribute information existence flag.
