I know there is an old thread about the private folder and a few other threads on the internet but I am still confused on why it is happening. People say is virtual memory being backed up or whatever but i don't how to stop the virtual memory from eating up all my HD space. I have a MBP 2.16 GHz core 2 duo with 2 gigs of ram with 120 gig HD. I have 56 gigs of free space when i boot up, but after 3 days of not downloading anything and only really using Safari and using iTunes, i now have 46 gigs. My computer countinues to run very slow as my HD space is taken up. Before, I wouldn't restart my computer for weeks and it would be fine but lately, it seems i need to restart every 2 days. Can anyone give guidance to my situation? Thanks.
