What is an M3UP file?

An M3UP file is a media playlist, used to play a series of audio and/or video files. It contains a list of paths to the songs, movies, or other files included in the playlist. If the files are hosted on the Internet, these paths will be URLs. M3UP files are more commonly saved with the .M3U8 extension.

Many media players can use .M3U format playlists to load and play a set of media files. For example, you can create an M3U playlist that references several Bob Dylan songs saved on your computer and then load that playlist in VideoLAN VLC media player to play those songs in sequence.

M3U playlists that use UTF-8 character encoding are commonly saved as M3U8 files, to denote that they use UTF-8 encoding. Less commonly, UTF-8 encoded M3U playlists are saved as M3UP (M3U playlist) files.

NOTE: The M3U format can also be used to create playlists that reference video or audio files that are hosted online. Loading these playlists allows you to stream the referenced files from your media player.

How to open an M3UP file

Many media players, including Microsoft Windows Media Player (Windows) and VideoLAN VLC media player (multiplatform), can open an M3UP file and play the playlist it contains. In some cases, you may have to change your M3UP file's extension to .m3u8 before opening it.

You can also open an M3UP file in any text editor, such as Microsoft Notepad (Windows) or Apple TextEdit (Mac), to view the text it contains.
