As I said before, I went into Tools and chose the Drive Wiper. This utilty is currently wiping the free space on my C drives. Choosing Settings/Wipe Free Space Drives does not work. It cleans normally but fails to go on to wipe the free space. Instead, the program just closes. I learned to go to Tools instead from a post in the forum. So, this does not appear to be a new issue or just happening to me.
