Guess what? mIRC is not a file sharing program!.

If you don't like that answer, then please feel free to earn some money, and exchange that money for the things you want. It's a great system, I call it "buying"

Sorry for the sarcastic answer, but you really shouldn't be trying to break the law (yes, it is illegal) - IRC means Internet Relay
Chat and it should be used for just that, chatting, as should the program(s) which run it, such as mIRC.
Happy
chatting!
