By the way, since you are studying how everything works, this is some basic info about the song file types, from FAQ #85.

85. Explain the different file extensions that Band-in-a-Box® uses for song files.

Band-in-a-Box® song files end in a ?G? file extension.

If the song has a melody, the extension begins with an 'M'. If the song doesn't have a melody, it begins with an 'S'.

The second letter of the extension is always a G.

The third letter refers to the style that the song uses. 1-9 and A-N refer to the original "built-in" styles (for example, ZZJAZZ.STY, ZZWALTZ.STY) and U refers to a "User" style (actually, any other style).

Example 1: MySongTitle.MGU

The M tells us that the song has a melody.

The G is always present in song names telling us that it is a song.

The U tells us that the style is a user style.

Example 2: MySongTitle.SG1

The S tells us that the song doesn't have a melody.

The G is always present in song names telling us that it is a song.

The 1 indicates that the song uses Style #1, which is Jazz Swing (ZZJAZZ).

Another song file you may encounter is MGX. This refers to songs that contain an entire MIDI file on the Melody track. For example, if you had used File | Open MIDI file (Band-in-a-Box® 2004 or later), or the MIDI file Style Wizard (Band-in-a-Box® 12 and later).

The song files are quite small. This means that you can store hundreds or thousands of songs without using up too much of your hard drive space.
