Installing game with Windows 7 filing system

Hi:

I am interested in buying another copy of Windows 7. However, when I installed my favorite game, the filing system on Windows 7 will not let me install the additional software I want to install for the game randomly!!

(The disk has several lines of data on it but when it is installed and I want to install additional software in the folder to play other portions of the game, the new software installs above the bottom line of the data in the folder instead of below the bottom line of data. This does not occur when installing the game and additional software on XP.)

Is there a way to eliminate this alphabetical filing system so I am install files randomly?

Thanks for your assistance and I look forward to your input.

Regards.
