Compact Disc plus Graphics (CDG) files contain a low-resolution graphics along with an audio track. CDG files are the preferred format for karaoke programs where people sing along to a music track while viewing song lyrics on a screen.
If you have a laptop computer with Windows Media Player or another popular media viewer installed, you can listen to and view karaoke CDG files. To play the files on your Windows laptop, however, you will first need to install a free codec to add support for the files.
Go to the Karaoke for DirectX website and download the "Karaoke for DirectX" codec for Windows (see Resources). Save the file to your laptop.
Open "Computer" or "My Computer" and browse to the "Karaoke for DirectX" set-up file. Double-click the file and follow the on-screen instructions to install the codec on your laptop. Reboot your laptop if prompted to do so.
Browse to the folder on your laptop that contains the karaoke ".CDG" file you want to play in Windows Media Player or your default media application.
Right-click on the karaoke CDG file. Scroll to the "Open With" option and then click the "Windows Media Player" option (or your default media player if you use another application). Alternatively, insert a CD with CDG files into the optical drive on your laptop, and then open the disk in "Computer" or "My Computer."
Wait for your default media player application to open and begin playing the CDG karaoke file. Once the file starts playing, you should be able to hear the music track and see the song lyrics on the viewing screen.
