I am running a new program called Diskeeper 2008. It has analyzed my computer and it shows I need to do something I don't know how to do. Maybe someone can assist. First, my computer details:

Windows XP
My C drive is 104 GB and has 61% free space. My D drive is 7,235 MB and only has 5% free space.

I am getting the following error message: "Little or no fragmentation detected on this volume. Free space on this volume is critically low and performance is suffering because of it. Take actions to free more disk space."

Ok, I am far from a computer expert. What steps can I take to do this? I look at this drive and I don't recognize anything on it so I am not sure how to delete anything if that is what I am supposed to do and I have no idea how to add to a D drive.

Can someone help me? Thanks in advance.

Steve
