I may not be explaining this perfectly as I use a mac and afaik m3u files are a windows only thing.
Furthermore I dissabled the Limewire player the second day I had it as the sound from it did my ears no good
Enqueuing is the making of a playlist for the limewire player. These files that you queue are m3u playlist files, which I believe link somehow to the mp3s.
Did you find tools/options/preferences > saving >save file. Can you write out what it says there.
Your mp3 player is not concerned with limewire, the limewire playlist or player. It is only interested in the mps files, and I think all you have to do is find them
