Prior to Windows, there was a MSDOS, MSDOS is a basic operating system exactly where you are able to manage programs and information files. In order to access the MSDOS command prompt window on Windows 95/98/ME/2000/XP/2008/Vista/7/etc., please go to "start" -> "Run" and type "command" or "cmd" command, press "Enter" key, you will able to launch a DOC window, then you can run command line applications in this DOS window.
The MSDOS environment is simpler than Windows. There are no icons or menus to click on. In fact, you can't use your mouse at all. You've to enter commands at the command prompt. It is going to look some thing like this:
C:\Documents and Settings\Administrator>
This is indicate that you are on the C drive in the "C:\Documents and Settings\Administrator" folder.
If you wish see all files in this directory, type 'dir' without the quotation marks and press enter. For example:
