Sorry, my last answer was missing a ToString:
Run["cp franc.data franc$"<>ToString[j]<>".data"]
You might also want to save it to that name in the first place, instead
of copying. You can StringJoin right away and use the resulting string
directly in Put[] (>> is just a shortcut for Put):
Put[franc,"franc$"<>ToString[j]<>".data"]
