I was calculating how much hard drive space I had and found.

Everything under "add and remove programs" except windows update, Roxio and Bluetooth software

Add & remove programs added up to - 1.01GB
Roxio and Bluetooth probably use- 2GB (I'm guessing because windows didn't specify)
Windows update- 4GB (I'm guessing again because windows didn't specify)

Documents- 1.12GB
P2P program- 7.583GB
P2P Downloads in Progress- 17GB (when completed)
Music- 415MB
Pictures- 2MB
Desktop- 202MB
Total=39.72GB

My total Hard drive=80GB
