As said a kazillion times before, mIRC is not a filesharing program. It is not intended as such, even though it can be done. I seriously doubt support will ever be added for anything that would make mIRC a better filesharing program. There's other ;programs for that. mIRC is for chatting (hence the C), not filesharing.
