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.
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.
