Open-source client for the Direct Connect network
DC++ is a free, open-source client for Windows for the Direct Connect (DC) file-sharing network, a decentralized system built around user-operated hubs. Designed for community-driven file sharing, it allows users to connect to multiple hubs simultaneously, search across connected communities, and exchange files while participating in integrated chat.
Distributed under the GNU GPL and free of ads or bundled software, DC++ combines segmented downloading, download resumption, Tiger Tree Hash (TTH) verification, and automatic router configuration via UPnP and NAT-PMP. Its balance of configurability and usability makes it a long-standing and widely adopted client within the Direct Connect ecosystem.
After installation, users select a nickname and configure one or more shared directories, which determine the files they make available to others within connected hubs. Because each hub is independently operated, rules and naming requirements may vary. Upload slots are customizable, allowing users to control how many simultaneous uploads they provide and manage their bandwidth accordingly.
Getting started and navigating hubs
DC++ includes a public hub list that lets users browse or search for communities by name or description, making it easier to find hubs aligned with specific interests. Since searches are performed across connected hubs, joining larger or more active communities typically expands the range of available results. Integrated chat supports public discussions and private messaging, and many hubs also enable text-based commands through bots, depending on their configuration.
Network connectivity and performance considerations
Building on its automatic router configuration via UPnP and NAT-PMP, DC++ also includes NAT traversal support to help users operate behind routers or firewalls. These features simplify configuration in typical home network environments and reduce the need for manual port forwarding.
To maintain transfer reliability, DC++ supports download resumption, allowing interrupted files to continue without restarting. In addition, segmented downloading enables files to be downloaded in parts from multiple sources when available, which can improve overall transfer speeds. As with most peer-to-peer systems, performance ultimately depends on source availability, hub activity, and individual bandwidth settings.
DC++ is available for Windows 7 SP1, 8.1, 10, and 11 in both 32-bit and 64-bit editions. The optimized build requires a 64-bit CPU with SSE4.2 instruction support, while the legacy build requires a CPU with SSE3 instruction support.
Focused file sharing for hub communities
DC++ remains a reliable and well-established client for users of the Direct Connect network. With multi-hub connectivity, segmented downloading, secure communication, and flexible bandwidth controls, it delivers a focused file-sharing experience centered on community interaction. Its open-source foundation and ad-free design further reinforce its appeal, making it a practical choice for users who value structured, hub-based peer-to-peer sharing.
