M3U is a computer file format that contains multimedia playlists. It originally was designed for audio files, such as MP3, but various software now uses it to play video file lists. M3Us can also point a media player to an online streaming audio source. Numerous media players and software applications support the M3U file format. ==File format== An M3U file is a plain text file that specifies the locations of one or more media files. The file is saved with the "M3U" or "m3u" filename extension. Each entry carries one specification. The specification can be any one of the following: * an ''absolute local pathname''; e.g., C:\My Music\Heavysets.mp3 * a ''local pathname'' relative to the M3U file location; e.g. Heavysets.mp3 * a URL. The M3U file can also include comments, prefaced by the "#" character. In extended M3U, "#" also introduces extended M3U directives. One common use of the M3U file format is creating a single-entry playlist file pointing to a stream on the Internet. The created file provides easy access to that stream and is often used in downloads from a website, for emailing, and for listening to Internet radio . If an m3u file is edited with a text editor, it must be saved in the Windows-1252 format, which is a superset of ASCII. "m3u" files properly use the Latin-1 character set. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「m3u」の詳細全文を読む スポンサード リンク
