hello. i know the hard drive's space drops down after a scan but i can follow the following procedures to free it up (below). mine went from 40+gb to 67gb after doing it. but then i did a second scan right after the procedure and the hard drive's space drops down again and i did the procedure again BUT this time the hard drive's space did not go back up to 67 and it remained at 58gb. can someone tell me what happened and how could i get the 10gb back?
