This type of removable media is exactly what it sounds like; a data disc (CD or DVD) containing files (and possibly folders). When this type of disc is loaded into the Project window by selecting Load Disc on the Project menu (please refer to the topic Working with projects for more information) CDGFix 3 Super will scan the files and folder structure on the disc looking for recognized Karaoke file formats. As known file formats are found the tracks are listed in the project list. This process gives the same result as selecting Add Folder on the Project menu and selecting the root folder on the data disc.
