Yes, CCleaner can overwrite the free space. Once is enough. If there are files that you want to overwrite you can send them to the Recycle Bin and then

allow CCleaner to overwrite them while cleaning out the Recycle Bin.

 

Keep in mind that ISPs, phone companies, search engines and websites have stored information, too.

There is also a free utility, called Eraser, that will shred your files such that they cannot be recovered, ... well at least by ordinary folks.  Don't know what NSA could do ... ?

 

Have a great day.

Shred files and wipe disks | BleachBit  (I've used BleachBit for several years in both Windows and Linux)

 

QUOTE: Normally when software deletes a file, only the "metadata" is erased: that means the complete contents can often easily be recovered, so BleachBit (and similar applications) offer secure erase features (also called secure wipe or file shredding) to permanently remove data. Some applications even advertise "advanced" erasure methods referencing important names in security such as Gutmann, the United States Department of Defense, and the NSA, but these references often mislead people to waste time on snake oil technological remedies while ignoring important basics. Any product or method suggesting a convenient, comprehensive solution to security is deceptive: convenience and security oppose each other. This guide will explain how 1 pass is enough, but 35 passes are not enough. Regardless of the tools you use, please read this guide carefully and completely.

 

Myths and legends

Most of the confusion regarding the topic of data remanence (data left behind after it is deleted) is because of myths and urban legends. Before discussing what is true, let's preview what is not:

  • False: Data on a hard drive overwritten by one pass can be recovered by powerful government agencies
  • False: Overwritting data with multiple passes makes it harder to recover than overwritting it with a single pass.
  • False: Peter Gutmann thinks data should be overwritten with 35 passes to prevent recovery.
  • False: Peter Gutmann's paper applies to modern hard drives ("modern" meaning manufactured after the year 2000 or so).
  • False: There are methods approved by the DOD (5220.22-M), NSA, and Gutmann to shred files.
  • False: The United States Department of Defense approves of overwriting (of a whole hard drive) as a data sanitation method.

Anyone that doubts one pass is enough, click on the link above for much more info.

Buddy, I'm going to do the OnePass, is ccleaner the best tool for wiping free space?  And, should that be done in Safe Mode?

Cleaning the free space is a time consuming task. I'm sure there is some risk....not sure of how much...involved.

I will not recommend any program over another.

I would only consider overwriting the free space if the computer was leaving my possession and for whatever reason didn't want to reformat and reinstall OS.

I would suggest defragmenting before overwriting free space on a disk drive....not an SSD.

I would think it best to run the defragmenter and overwrite in safe mode.
