The istat pro on my dashboard as well as warnings from the system are telling me that out of my 1 gig of ram there is no free memory space. Also, most of my hard drive is full and i want to see what is taking up all the space. I was in the store getting something repared once and i saw the person at the genius bar opening some window that showed which files and folders were using what amount of space. I am wondering if anyone knows how to access this, and also see what activities are using all the ram. I already tried the activity monitor which wasnt very helpful.
