.m3u

If u are a windows user, you certainly would have made a media player play-list or at least seen it.Even some torrent downloads have a play-list in the folder.

Ever wondered how it is stored or how to make one without using media player.The playlist is stored in the form of a file with extension '.m3u'. They contain nothing but the path of the songs you selected, in order of your selection. Creating one is also very easy.
Creating a play-list
Lets make a play-list in a folder containing 2 media files abc.mp3 and def.mp3.
First of all create a new text document.
give it any name say playlist.txt.
Now just enter the names of your media files in it. In the order of your choice.
Now change the extension of playlist.txt to .m3u

There it is. Your play-list is ready. Double click on it and listen to your songs.
