Ah you can't. %x substitution only works on primitives and char arrays, 
meaning, numbers of various sizes, letters and strings of letters.
There's also date formatting (strftime), but that's about as far as it goes.

A file is not a 'thing', it's a container of things, so it's very 
hard 'format'.

But like Eric said, it helps to know what language you're using and what you 
got so far and what you want to do.

Problem with today's modular software: they start with the modules
    and never get to the software part.
