There is only one file type that uses the .MPCPL extension:
Media Player Classic Playlist
Playlist of media files created with Media Player Classic (MPC), a popular media player for Windows; contains a list of media files that can be played back in sequence or in a random order; may include both video and audio files.
Media Player Classic playlists contain references to the media file locations, rather than the media itself.
