With Nero Burning ROM you can compile CDs that include both audio and data files.
The following compilation methods are available:
Mixed Mode CD 
A Mixed Mode CD includes the data and the audio files in one session. CD EXTRA includes the audio files in the first session and the data files in the second session.
The procedure for compiling the audio and data files is basically the same as the procedure for compiling data or music CDs. Please be sure to select the corresponding entry in the New Compilation window. The selection screen includes a compilation area for audio files and one for data files. The compilation can only be burned if files have been added to both the audio and the data compilation area.
