Just trying to understand how this works.
My system has been formatted to NTFS. What's the difference in wiping free space with the various options and does it affect system performance? In terms of visited web pages, once they are deleted, I guess they are moved to free space on the C drive, so the only way to be sure of removing complete trace of them is to do a 3,7 or 35 pass wipe?
Are there any other settings that I should select in CCleaner just to make sure? Obviously reinstalling the OS and fully wiping the drive is an option but very tedious...
