i only have a limited space left in my c drive. It is filling up pretty quick. I tried cleanup defrag. et cetera. I watch movies online a lot such as youtube and movies. What could be affecting this?

Please post to this thread rather then starting new ones on the same issue. Thanks.

If someone has a new idea I'm sure they will post it here.

I still suggest adding a new hard drive.
