CCleaner drive wiper always wipes MFT free space whether or not the "wipe MFT free space" option has a check mark. I'm using v4.16.4763 (64-bit) on Windows 7 Home Premium wiping my "C:" drive free space. I would like to turn off wipe MFT free space by removing the check mark because it adds many hours to the wipe process. Please advise. Thanks!
