How can I create an M3U playlist in Windows Media Player? First, create a new playlist in WMP and add songs.Once you have them together, free file converter software can be used on the files to convert them to the format you want them to be in, like MP3 to WAV, MP4 to AVI, etc. This technically isn't an M3U file conversion, but if you want to gather all the audio files that an M3U file is referencing, and copy them to a single folder, download and use the M3UExportTool.
