Yeah, yeah, and your generator is a (pseudo- or even worse: real) random generator. Nope. Read some information theory on why
that is not possible without cheating (e.g., tricking the operating system into believing the files have
a different size than they have).
It is really a pity that you said "less than". If you
had said "less than or equal" I would have requested
a file of size zero and sent two zero size files back.
Damn ... ;-) ...
