DC++ application is an open source file sharing client for Windows for the Direct Connect and Advanced Direct Connect network. Direct Connect allows you to share files over the Internet without restrictions or limits.

The DC++ client is completely free of advertisements and has a nice, easy to use interface. Firewall and router support is integrated and it is easy and convenient to use functionality like multi-hub connections, auto-connections and resuming of downloads.

DC++ is a highly ranked piece of software among the projects hosted at Sourceforge. With more than fifty million downloads, new users continue to find benefits from the software every day. The program is, based on observable factors, the most prevalent client on the Direct Connect network.

DC++ is free software, written in C++ for the Direct Connect and licensed under the GNU GPL 2.

DC++ Features:

  • No ads, spyware, or bundled software that you don’t need

  • Joins multiple hubs at the same time
  • Multiple protocol support (ADC & NMDC)
  • List of bookmark-like favorite hubs and users
  • Shares large files and many files per your organization scheme
  • Tiger Tree Hashes (TTH) used for file integrity
  • Search across all (or selected) connected hubs by file type, size, name or hash
  • Resume of downloads, with optional automatic search for alternate sources by TTH
  • Logging options and configuration for chat, private messages, downloads, and uploads
  • Automatic connectivity setup with autoconfiguration of UPnP and NAT-PMP routers
  • MAGNET link support for linking to specific content
  • Automatic and manual download priorities
  • Saving of user’s file lists for browsing and queueing

Changes in DC++ 0.880 (2022-10-20):

  • Upgrade license to GPLv3 for future license compatibility with some libraries
  • Add OS and UAC compatibility manifests (emtee, iceman50)
  • [L#1774502] Restore automatic downloading of up-to-date GeoIP databases
  • Set cached hublists to expire in 24 hours, keep them longer only in case of download problems (emtee, rolex)
  • [L#1979900] Prefer attempting outgoing connections on IPv4 when there’s no IPv6 connectivity (emtee)
  • Introduce the naming “Optimized” and “Legacy” for the 64-bit and 32-bit builds of DC++ respectively; the former gains advantage of modern OSes and hardware while the latter makes DC++ remain compatible with the 32-bit architecture and / or old hardware.
  • Installer: detect available CPU features and offer the best DC++ binary for the current system (emtee)
  • [L#1970416] Set the focus properly on the active window at startup (emtee)

  • [L#1682791] Block possible unencrypted direct private message connection attempts (fix adapted from AirDC++) (emtee)
  • Upgrade compiler for better performance; allows further optimizations to modern Windows versions (cologic, emtee)
  • Allow copy of hub address with keyprint on secure hubs (code adapted from AirDC++) (emtee)
  • Require SSSE3 for 64-bit builds (cologic)
  • Documentation and translations updated as usual, thanks everyone
