An FPL file contains a playlist used by Foobar2000, a freeware multimedia playback application. It stores information about a playlist, which includes the number of tracks, locations of audio files linked in the playlist, and the artist, genre, and title of each track.

Foobar2000 allows users to create playlists to organize audio tracks into a list based on certain criteria. Some examples of playlists include audio tracks with fast tempos for dance parties or audio tracks with slow tempos and no words for meditation purposes. Playlists saved in FPL files are designed to only be compatible with Foobar2000. The closed format allows Foobar2000 to more quickly read and write FPL files. To create an FPL file in Foobar2000, right-click on a playlist, then select Save playlist. To open an FPL file in Foobar2000, select Load playlist and choose the FPL file.
