EiskaltDC++ is a multi-platform, open-source file sharing application based on the popular Direct Connect protocol. It allows users to connect to a network of other users who are sharing files through a decentralized peer-to-peer network. The application is light-weight and highly customizable, with features such as chat, file transfers, file search, proxy support, and more. EiskaltDC++ also integrates with media players such as VLC or Media Player Classic, allowing users to stream media directly from the application. It also supports UPnP and NAT-PMP technologies to allow easier connections, making it easy to connect to other users and share files.
Discontinued The project seems to be abandoned. The latest version, 1.1.0, released in April 2011, can still be downloaded from Launchpad.
