DC++ is a client for the Direct Connect file sharing network. The Direct Connect network is a decentralized network, made up of individual servers (hubs) that users join to share files with other members on that hub. Each hub is individually run by a fellow user of the Direct Connect network, and may have certain themes to the content on the hub. Hub owners set up rules to regulate their hub as they see fit.
DC++ is, based on observable factors, the most prevalent client on the Direct Connect network. Below are some of its features:
