Abstract
An audio multimedia player has dual access modes for navigating between track selections contained in a large storage media, such as a compact disc CD-ROM having compressed audio files. The disc may includes numerous directories for organizing the audio files, but the player has insufficient display resources to show the directories themselves. In a flat file mode, all target audio file on the disc are included in a sequential numbering scheme which ignores any directory structure. In a directory mode, all directories are collapsed onto a single directory level in which subdirectories are moved up to the same top level as all other directories. The directories are sequentially numbered and then the target audio files within each directory are sequentially numbered.
