I open Computer and C says it only has about 15 gigs free, but as you can see in the images everything else say that I'm only using a bout 88 gigs out of 279 available. I have done a preboot defrag, I have checked each of the main folders on C by hand and all totaled come up with just about 88 gigs used. On a side note I uninstalled AGV Internet Security because it was eating up 59 gigs of space with it's log files, but once I rebooted even though all of AVG was gone there was no change in how much space windows was saying is being used. I can simply rerun windows and reinstall my programs and do my tweaks, but i'd like to avoid that if possible. any ideas and or help would be greatly appreciated.
