Oh? Invision isn't any more a filesharing script than mIRC is a filesharing app. It has the ability and makes it easier than mIRC's default, but it has much more than filesharing options. The majority of the script has nothing to do with filesharing. We also don't support downloading or sending of warez/mp3s.
Besides that, even if we did, the rules here are specific about such things.
