AirDC++ 4.20 – Advanced Direct Connect Client

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

AirDC++ is the ultimate, easy to use file sharing client. It allows you to share files with friends and other people, for example, with people who have a common interest from all over the world. Also AirDC++ can be used within local or wide area networks.

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.
