Hello, you experts in the know, please help me. I followed all the tips on the My Digital Life site to shed unnecessary files from my Vista. When I deleted the Shadow Copy, it dramaically reduced my free H.D. space (about 25GB) but then after I strenuously deleted little files (from Repository, from example and other files), I found my computer gained 3 GB. I really do not understand this. Where did they come? I did install some new little softs like Take Ownership and Wise Cleaner which was recommended on the website, but they should not add up to more a than a few MB, let alone 3 GB. Please enlighten me.
