AirDC++ is a free and open source peer-to-peer file sharing application that allows users to easily share digital files, such as music, movies, applications, and documents over a network. It is based on the Direct Connect protocol and uses a distributed hash table to search for shared files among users. AirDC++ is cross-platform compatible, meaning that it can be used on Windows, Mac, and Linux operating systems. AirDC++ is user-friendly and easy to use, allowing users to quickly connect to other users and start sharing files. It offers a simple user interface and allows users to have multiple transfers and searches running simultaneously. It also includes a built-in chat system that allows users to communicate with one another. AirDC++ also has several advanced features that make it useful for more experienced users. For example, it includes a bandwidth manager that helps users manage the speed of their downloads, and a built-in file manager that allows users to organize the files they are sharing. In addition, it also has a secure encrypted connection that helps protect users' privacy.
Discontinued The project seems to be abandoned. The latest version, 1.1.0, released in April 2011, can still be downloaded from Launchpad.
