What is the .M3U File Extension?

.M3U File Extension Description:

The file extension M3U was initially familiar with the Winamp Playlist file. But due to its popularity, various MP3 players as extensions to their playlist files have also adopted the M3U file extension. Microsoft Windows Media Player, MusicMatch Jukebox, QuickTime Player, RealOne Enterprise Desktop, and Roxio AudioCentral Player, are just few of the many MP3 players that use the M3U file extension.

Playlist files having the M3U file extension in MP3 players are lists of multimedia files that are grouped together, and played in a single row without the need of adding new songs to them. Usually, playlist files are used to group different genre of music like Rock, R&B, Acoustic, Rap Metal, Punk, Mellow, Country, Blues, and Folk. Sometimes, playlist files can be associated with a certain album, a certain artist, or certain ratings. Making playlist files depends on the user. After he has made his own playlist files that will be saved with the M3U file extension, he can then use the playlist files to play a group of multimedia or songs.

The file extension M3U is a shortened name for MPEG3 (Moving Picture Experts Group Audio Layer 3) URL (Uniform Resource Locator). This file extension is only a plain text file, but it contains the locations of all the media files included in a certain playlist file. Each audio file is given a certain line location, which an MP3 player can call upon when it's time to run the audio file.

With the M3U file extension, users can even compile songs that are from different file locations, and without eating too much hard disk space. When a file with the M3U file extension is played or called upon, the MP3 player will read the content and instructions enclosed in that file. Then, it will execute all the songs that are listed in that file by locating the file path recorded in the playlist file.

Simple problems with M3U file extensions only occur when the user deletes a certain audio file, or moves it from its original location. The MP3 player will not be able to locate the file and will encounter an error. However, the user can always modify what can be included in a certain file with the M3U file extension to correct the error.
