When downloadable audiobooks were first released, some publishers had versions of their audiobooks already formatted for CD as one of the primary formats for audiobooks. These data files were already divided into 45-minute CD-length audio parts, so some publishers offered those files to OverDrive for licensing to libraries and burning by library users. Offering data in this format also discourages piracy.
