Okay, here is the situation. I have 2 hardrives in my rig C: (main) and D: (music, videos, and battlefield 2142) My C: really isnt supposed to have any really big programs on it, except that it does have World fo Warcraft on it, and its numerous patches, along with microsoft office and a few other minor things. The problem is my computer runs a bit slow at times and I heard that once the hard drive gets past around 75% filled, this can slow that machine down. Well my hard drive is at 91% full, and I cant seem to figure out what is on there that is hogging teh space. I did disk clean up and defrag and it doesnt free much up. MY suspicions is that I hard a hard time installing BF2142 due to installation bugs, and while I ended up trying to install/reinstall it on both drives, it was a total mess, and was advised to clean out my registry, but use "system restore" in case I messed up my machine in the process. Make a long story short, I think I have hidden "restores" that are not needed, that are clogging up my drive. so.... after all of this I could use some advice on: 1) what is the best way to see what is actually tying up all the space? 2) If saved "system restores" DO TAKE up space which I was told, how do I find them do get rid of the 3 or 4 I have? Or anything else would be valuable. thanks!
