The primary purpose of Interleaf files is to split various file formats into smaller chunks that are interleaved together so they can all be read as one continuous stream. For example, a chunk of voice data may be followed by a chunk of matching animation data or a bitmapped graphic. This is done to reduce the amount of seeking around the disc for assets since CD-ROM speeds of the era were generally very slow and end-user hard drive space was usually too limited to store much game data.
