How do I make .ml files?

[nitt]

I was using the Mission Editor, and then when I saved the level it only gave me a .mis and  .ter file. But how do I make a .ml file for the level?

You really don't need it anyway, you just skip the one-time "Lighting mission" if you do package one.

Plus, everytime you hit Alt+L, you'll get a new file, which can spam the folder.
