Example of a basic plugin header:

Because WPL files store the path to a file, moving the actual music file will break the playlist. For example, if a WPL file points to C:\Music\Song.mp3 and you move that song to C:\NewMusic\Song.mp3 , the WPL file will not be able to find it. Windows Media Player will skip the track or show an error. wpl extension
