FulDC++
A modern, fully dark direct-connect client for Windows — built on AirDC++, and happy to run right alongside it.
Version 1.10 · Windows 10 / 11 · 64-bitWhy FulDC++
Everything you already know from AirDC++ / StrongDC++, plus a genuinely dark UI and a stack of quality-of-life features.
18 languages, no restart
Pick your language in Settings and the whole interface switches the moment you press OK — menus, tabs, lists, dialogs and the chat already on screen.
Rich text in chat
Headings, bold, code blocks, quotes, lists and inline pictures on hubs that support it, with a Markdown composer and live preview. Off by default if you'd rather not.
True dark theme
A fully independent dark mode — title bars, menus, lists and chat — with 52 presets and a custom palette editor. Toggle live, no restart.
Runs beside AirDC++
Its own instance and profile folders, with a one-time automatic import of your existing AirDC++ settings. Try it without giving anything up.
Plugins, one click
Browse and install native DC++ plugins from inside the client. The list is signed and every download is checked against a pinned hash.
Web extensions
Node.js extensions installed from a signed catalogue — release checkers, share tools and chat commands. Browse extensions.
Chat triggers
Keyword and regex chat automation with capture groups, away-only mode, fire stats and import/export.
Auto-recovery
A watchdog restarts FulDC++ automatically if it ever crashes or stops responding, so long sessions stay up.
Self-updating GeoIP
Built-in IP geolocation (MaxMind GeoLite2) with a configurable, self-refreshing database.
