They have had extensions in the command shell ever since Windows 2000, at least. At the Windows 2000 prompt, the extended mode seemed to me to determine how POSIX-like you wanted the shell to be. Now I want to read up on the Windows 7 command prompt, since I now own two PC's with Win 7 64-bit at home. Here at NLS, we have just moved from Win 2000 to Win XP!

I make use of the same old commands, but this page sounds like they might just be aliases to command applets. If so, why are some old commands still restricted to short filenames? It also sounds like there is nothing that can be done about the incompatibilities. Additionally, there is something referred to as extensions, which need to be enabled for some commands to work as expected! How do you know if extensions are enabled? By the way, the Vinux 3.0 Virtual Edition has been released! I am downloading right now. Will forward release in next message.
