Toolserver:WinSCP

WinSCP is a tool which can be used by Windows users to transfer files to and from the toolserver, as well as edit their files on the server and navigate around in a familiar Explorer GUI.

UTF-8
WinSCP (predictably) has poor unicode support. If your files are unicode, set up an external editor like Notepad++ instead of using the internal editor, which fails on unicode characters (even if you choose a nice unicode font like DejaVu Sans - it's not just the font).
