I am running win 7 pro and recently I deleted more than 20 gbs of date files and programs from my downloads folder, however there has been no change to the properties of my C: drive. I have run scans with hitman pro and it show bad files in the downloads folder that were deleted. Any ideas why files deleted would not change storage capacity and why they would show up on scans when there is no evidence of the file in the folder, thanks.
