Mintty is a terminal emulator for Cygwin and MSYS with a native Windows user interface and minimalist design. It is based on parts of PuTTY by Simon Tatham and provides xterm-compatible terminal emulation, but does not require an X server. Its features include a simple options dialog, Unicode support, fullscreen mode, drag & drop, and window transparency.
sftp4tc is a file system plugin for Total Commander that allows SFTP sessions to connect to your Unix/Linux servers. It supports Unicode file name translation, server-to-server copy, and all usual operations. Because it is based on PuTTY, you can use all your configured servers from PuTTY, and it also supports the Pageant private key agent.
