Hello,

İn CCleaner,under Optons>Settings,Under 'Wipe Free Space drives'

the option to Wipe MFT Free Space is listed.

1. What does it mean and what does it actually do?

2.Why is it checked by default.?

Thank you

It overwrites file names and any file data in obsolete records in the Master File Table. It is quite safe and worth including if you're wiping free space.

fyi: On 9 August I discovered that Drive Wiper wiped the MFT even when Options\ Settings ☐Wipe MFT was unticked.

@ Kroozer, it normally does wipe MFT while wiping Free Space.

Do you mean that you ran Free Space wiper & it wiped MFT?
Or that you ran CC & it ran free space wiper without being checkmarked?

If option 1, that's normal.
If option 2, have you tried also unchecking to wipe C: under CCleaner tools?

As I understand it Drive Wiper wipes the MFT by default. It does not take any notice of the Wipe Free Space settings.

I would be interested in knowing if anyone else has Wipe Free Space and Wipe MFT ticked by default (that is they didn't choose to do this, it seemed to be already selected)

Wipe MFT Free Space has never automatically enabled for me, I've always had to tick that setting for CCleaner to use it.

Piriform software help documentation.

CCleaner is NOT a malware removal tool.

Don't PM me for advice or help! I'll only ask you to read forum rule #15.

Old versions of CCleaner can be found here on FileHippo.

If you open the folder holding CC portable, rename ccleaner.ini to something safe, then run CC, you will get the defaults. In the Options/Settings panel Wipe MFT and drive C are checked, but Wipe Free Space in the Cleaner Panel isn't. To the original poster, I haven't the faintest idea why.

New to the forum so I hope I did this reply correctly lol

In answer to your question YES to WIPE MFT IS checked by default and NO WIPE FREE SPACE is not checked by default.
Using W7 64bit and version /v3.19.1721 (64bit) CCleaner.

devzangel, are you also experiencing the issue as described thus far?

I've been using CC for years and yesterday stumbled upon this part of the GUI that I'd never seen before. I googled and came upon this thread (may be more recent) and am more confused. By default, Normal file deletion was checked (good) and by default, Wipe Free Space drives © and Wipe MFT Free Space was checked (not sure good or bad). I've unchecked both the C MFT. The thing is I'm running a SSD so I need to know what I should do. Thank you!

do not wipe an SSD at all ever. Until you are done with it.
SSD have limited amount of times data can be written.
