If you have some initialization cells (Cell -> Cell properties) in the notebook, Mathematica will ask you before saving whether you would like it to automatically maintain a package (.m) file, with the same content as the initialization cells. If you enable this, then the .m file will be automatically updated whenever you save the notebook. > * Where to save the parent notebook itself (or a copy of it), > as an unconverted notebook. The .m file will be in the same directory as the .nb file.
