AirDC++ is a modern client for Advanced Direct Connect and Direct Connect networks. You can join “hubs” with other users, and chat, perform searches, and browse the share of each user.

AirDC++ is extremely high-performance with lots of advanced features. It has been tested to operate smoothly even with millions of shared files or hundreds of terabytes of data. The source code is available for everyone and there is no bundled software or advertisements of any kind.
