How to wipe free space?

Under CCleaner Settings there is an option "Secure Deletion" and "Wipe Free Space Drives". How do I execute this?

TIA

Hazelnut,

Yes, I eventually found it. I thought it would be more intuitive to have a button on the Settings page that said "Clean Drives Now" so it could be run on demand as an alternative to running it with the other cleanup options. :rolleyes:
