I have to say, the current cmd.exe that comes with Windows 7 is much better than the command.com I used when I was a system administrator 20 years ago. I could never had done those advanced tricks like extracting the folder name from a file path.
And when cmd.exe is not fancy enough, I fall back on VB script (like I did for
this script). For even fancier stuff like what you do with RW-Tools, I'd need a real programming langage like VB.Net, C++ or C#, but I'm just too lazy to go back to compiled languages.
