Wipe MFT Free space always active in CCleaner Bug Reporting Posted January 22 7 hours ago, Edward5932 said: This is exactly the problem. Wipe Free Space DOES wipe the MFT when this option is unchecked in Options/Settings. I think you may be confusing the two processes, which are entirely separate. Unchecking the Wipe MFT box in Options/Settings only applies when you run Wipe Free Space from Cleaner/Windows/Advanced. Using Drive Wiper will wipe the MFT whatever is in the Options/Settings box. If you don't want the MFT to be wiped then use WFS from Cleaner/Windows/Advanced.
