Hello,
I have Windows 7 Starter with Ccleaner 3.06.1433.
In Ccleaner, in addition to the other settings for cleaning, I also set the following:
Options/Settings:
"Secure file deletion"
"Gutmann 35 passes"
"Wipe free space drives Local Disk (C:)"
"Wipe MFT Free Space"
(However, I have not selected any drives in: Tools/Drive Wiper.)
When I run Ccleaner it completes quickly, and the report shown makes no mention of wiping Free Drive Space or of wiping the MFT Free Space; actions which I would also have expected to take some time.
How do I ensure it carries out the "Wipe free space drives Local Disk (C:)" and
"Wipe MFT Free Space" settings?
I look forward to receiving a solution.
Regards,
Robert333

Hello kroozer,
Many thanks for your reply.
Re: Action - Wipe free space drives:
I believe that I understand this better now!
Your instructions cause this particular action to be included in the routine/normal cleanse.
If we do not want this particular action included in the routine/normal cleanse (because wiping free space on drives can be time-consuming), we can choose to run this separately, at:
Tools > Drive Wiper.
(I notice that if we want to also configure this particular action to clear the "MFT Free Space" ("Master File Table Free Space"), we must set this at:
Options > Settings.)
Thanks for your help and speedy response.

35 or really anything over 1 secure, is overkill a will DRASTICALLY reduce the lifespan of your drive
