As of 2008, DC++ had around 90% market share of the Direct Connect community.[1]

DC++ is a free and open-source alternative to the original client, NeoModus Direct Connect (NMDC); it connects to the same file-sharing network and supports the same file-sharing protocol. One of the reasons commonly attributed to the aforementioned popularity of DC++ is that it has no adware of any kind, unlike NMDC.[2]

Many other clients exist for the Direct Connect network, and most of these are DC++ "mods": modified versions of DC++, based on DC++'s source code. A partial list of DC++ mods is given below. Some of these clients were developed for specialized communities (e.g. music-sharing communities), or in order to support specific experimental features, or perhaps features that have been rejected from inclusion in DC++ itself. An example of an experimental feature is hashing, which was initially implemented in BCDC++ and later adopted by DC++.
