DC++ is an open-source, peer-to-peer file-sharing client that can be used to connect to the Direct Connect network or to the ADC protocol. It is developed primarily by Jacek Sieka, nicknamed arnetheduck.

As of 2005, no official statistics exist to verify the proportion of DirectConnect users using DC++. However, it is generally believed to be the most extensively used by a large margin; administrators of popular public DirectConnect hubs generally agree^{[citation needed]} that DC++ is the client used by a significant majority.

DC++ is an 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 ^[1].

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++.

As of 2002, DC++ was still not accepted into some hubs because the number of slots is shared by all the hubs that the client is connected to. When the DC++ tag was added to the client, a hack was to remove the tag in an attempt to mask the identity of the client.

DC++ supports hub addresses in the following forms: dchub://example.com[:4012], with an optional port, and adc://example.com:12345. The dchub:// text indicates a hub using the NMDC protocol whereas the adc:// indicates an ADC protocol based hub. In the example, 4012 is the port where you can access the hub; the default port for NMDC hubs is 411.

An advantage of the open-source nature of DC++ is that several derivatives (mods) have been released which add features to the original client.

Many users send patches to DC++ which are included in future releases, but some features are rejected by the developer. Stated reasons for rejecting a patch are because they are coded poorly, or that the feature is frivolous, abusable or overly specialized, and does not belong in the main client. Examples include: upload bandwidth limiting (many users feel that upload bandwidth limiting is a form of cheating, while other users not using a full-duplex network connection can only achieve reasonable download speeds by limiting uploads), colorized chat, specialized operator functions (e.g. client/share checking).

The developers of some mods contribute features and bug-fixes back to DC++.

Below is a list of well-known mods and their features:

Features:

• Automatic active mode IP configuration (on hubs that support $UserIP2)
• Bandwidth limiting
• Chat coloring (e.g. nickname highlighting)

ApexDC++

LinuxDC++ is a Unix port that is based on the core of DC++. It has a rewritten user interface based on the GTK+ toolkit. It has not been released yet, but it is being developed actively and is available through CVS. Even though the name implies it is Linux-only, it works on other POSIX compliant operating systems, such as NetBSD and FreeBSD.
