|Are you confusing Memory (RAM) with hard drive space?|
What are you trying to achieve? Increase available hard drive space or reduce RAM activity?
What brand and model is your computer? Desktop or Laptop? What size is your hard drive? Did this system come with Windows 7, or was it an upgrade (and from what)? How much hard drive space do you have (GB and %)?
Please supply more details.
You have to be a little bit crazy to keep you from going insane.
If all else fails, read instructions.
