My laptop has 120GB disk space. It runs Windows 7. When I use 'SpaceSniffer', find out that 'System Volume Information' uses up 32G of space. And it has 5 files: 20.6 G, 3.4 G, 3.2G, 3.1 G, 2.4 G.
How can I recovered those space used by System Volume Information
Any my windows 7 restore point is already off.
