My OS is Vista I had a big 2gb .avi video file and decided to delete it. Before i did this the file size USED on my C: drive 114gb. I went to the recycle bin and clicked empty recycle bin expecting it would show a loading screen of the file being deleted but instead it just disappeared showing it was deleted. But then i checked my C: drive disk size and it was still 114gb. I need this fixed because my computer is becoming cluttered and i can't fully delete my files.
