My Vista is pretty new. OK....maybe....what? a month old? I have programs on here. Not too many though. Along with not too many files. I was very surprised when I start up and 19 out of 105 GB was all that was left. So i ran Tree Pro 4 and the size of my System Volume Information folder had literately 5x itself to 50.2GB. Im astonished and appalled. O If anyone has ideas, bring it forth cuz i need it.
