I have a refurbished laptop that I bought from a friend. Its mainly used for entertainment. As far as I can tell,there aren't any huge files on it. Ive tried disk clean and run all sorts of scans, but I can't find out where all my memory went. The C drive has 59.7GB used/ 10GB free. There is also a D drive.(Used 980 MB/ 68.5GB free) Do I need to move memory from the D drive to C drive? How do I do that. Would the scan log be helpful? Im running Windows 7 Ultimate
