Wipe Free Space

My first post - I have been using CC Cleaner for years and think it is great - highly recommended to numerous colleagues. Yesterday I accidentally hit Wipe Free Space before cleaning which I never do normally. It seems to have filled my whole hard disc. I have 100Gig disc which had about 40 Gig of free space. I had a message to say disc full and had to remove some folders to get it going again after running disc clean up and defrag. It is now working but I only have 3 Gig free space which is folders I removed.

It would appear that WFS has filled my disc - how do I recover the space please???? I run Microsoft Windows 7.

Did you by chance stop the Wipe Free Space while it was running?

If so that has the chance of it not removing the files it creates in the root of the hard disk, running it again without stopping it can remove those files and thus regain the original free space.

No left it running at night.

Local power utility supply outage causing abort/shutdown ?

Navigate to the root of the drive (C:\ usually) and delete the folders with names like ZZZzZZzzZzzZzzz etc. They were created by CCleaner.
