Let's say you have a computer with MS-DOS only on it and there are a lot of programs out there which require Windows 3.1 or Windows 95 to operate. You decide to upgrade your computer with Windows 3.1 because your computer is older and not quite powerful enough to run Windows 95. You install Windows 3.1 without any problem and after its done installing you check to make sure its on C drive by typing DIR at the C prompt. You notice there is a new directory called WINDOWS and sure enough, after changing to that directory and typing DIR again, lots of files fly by on the screen. Obviously, Windows 3.1 is a large program with many files. Creating its own directory keeps the subdirectories and files of Windows 3.1 organized and helps you, as the user find what you need.
