Create Con Folder

In windows we cannot use the name CON for any folder.. even tech from the Microsoft couldn't resolve it..
But here again, is the solution to create the folder named con and other system variables.

1) go to run dialog.
2) type cmd/command (command prompt gets opened)
3) go to root directory like C:\ or D:\ etc
4) type md\\.\\c:\\con ....(here is done)
5) check the folder on the respected drive.
