If you did file the axles you might have to make sure there's no square corners left after you have. It mightn't be anything to worry about, but corners are a classic place where cracks can start in metal things.
It's about the only thing I know to do with metal fatigue, and it might not be needed, but it'd be a pain to have your axel break while you're riding.
