Is there one of these files in RE3 pc?

What exactly do you mean? You do realise that kevstah2004 uploaded pictures of the items accessible in Resident Evil 2, right? These are not "files" per se, so I'm not sure what you're up to. :huh:

i have that resident evil 1.5 machine gun (below flamethrower) but it has no description, model, sound or animation. (sounds are just leon damage grunts)
