hey I have a macbook with leopard on it. I use it in my church for editing videos and designing images. I used to be a pc user so I bought an external hard drive an moved alot of my files over. I filled up the 200gb HD and after moving things I now have only 66gb of space. My question is where are the rest of the files that are eating up my HD and what can I do to speed up the macbook? I have 1.03 gb of system memory free.
