mIRC has a DCC feature that is intended for transferring files between friends or a group of friends. People now use it in a negative way and over time have given mIRC the reputation of a file sharing client. The number of people that use it in such a way though is irrelevant, that doesn't make it a file sharing client, and nor will it ever be one. Nor will we ever support it here, the official mIRC message board.
For the second time, please see
this.
