To use the auditioning player that is on the Song Cards, Music 1 has to have the full drive\path\file name for each audio file entered in the File field. There may come a time when you need to change the drive letter or even the full path File. And, some automation systems use the full path for their playlists, so a mass-change in the Cart field might be necessary. The video below shows how to do it. After the video, see the step by step graphics.
