Commander4K with the modern dark skin: two file panels

What it does

A mailbox, a photo gallery, an SFTP/FTP server, a Linux box over SSH, this PC's hardware or a dashboard of live cards — each is a folder, described by small .c4k files in it.
Streams huge folders and network shares without freezing the UI; LAN discovery (SMB, SSH, FTP, mDNS), archives, Windows Registry as a folder.
Out-of-process plugins in Python, Node.js, PowerShell or .NET with declared, audited permissions.
Built-in MCP server: Claude Code, Codex, Gemini CLI, Cursor or VS Code can build dashboards, skins and plugins, and the app asks before anything is saved.
Skins: modern, Norton Commander, Midnight Commander, Total Commander classic, or your own.
