4NT

4NT is a powerful alternative to Window's default command processor (CMD.EXE) for interactive and batch file processing. It makes the command prompt a truly useful place to work, and is compatible with CMD.EXE's syntax and commands.

Some ZTreeWin users believe it's the best tool ever after ZTreeWin itself and a natural complement to it. It is undoubtely a powerful productivity tool.

Price tag may appear expensive (75$) but must be evaluated in regard with huge productivity gain.

Portable version

There is a portable version of 4NT which makes it a wonderful personal tool for admin and power users. Instead of writing serial in registry, it does it on local INI folder. You have to download the regular package, then copy over a specially crafted version of 4NT executable. More explanation here and download portable 4NT executable here
