It took about 30mins to complete. It completed with no problem,Thank God. What is the benefit of doing this action? Does free space also become defragmented? Why wipe free space if it is free in other words empty? What is their to wipe? Is their any benefit to the system? I used this tool because it was their and there fore assumed it must be useful but how and why? I used the Drive Wipe In CCleaner to wipe About 50gb of free space. It took about 30mins to complete.

This is why CCleaner creates a large file, overwriting all of the 'free space' which isn't really free space but space on the hard drive allocated to being overwritten. CCleaner then genuinely deletes the file completely that it makes so the free space is actually FREE so when you turn on/run your computer, the processor has less Hard drive memory to read. Also, has anyone had CCleaner create a large file and then laptop runs out of battery so you can't locate the file it made to delete?

How long does it take?Can I manually delete the file?If so how? I used this and my free space on c drive came to 1.66 gb and its staying like that. CCleaner has not yet deleted that file.

Thanks for clarification of CCleaner free space area included and wipe security options. Exactly what I wanted to know. I said "US Military spec" but meant DOD (Dept of Defense). What you say about the Recycle Bin makes sense. What I vaguely recalled probably said CCleaner does NOT wipe files in the Recycle Bin (because the space is still allocated and not free). Alex S.

Thu, 02 Dec 2010 04:47:03 +0000 http://www.worthinstalling.com/?p=279#comment-1026 As I see it, CCleaner simply allocates ALL free disk space (regardless of the Recycle Bin, which is not actually considered free space) into a large file and then wipes it completely. The wiping options are: - a Simple Overwrite (1 pass), - DOD 5220.22-M (3 passes), - NSA (7 passes), - Gutmann (35 passes). At least two of these can be considered as "military grade".

I'm considering using CCleaner before I donate an old PC. One problem. I see no mention of the wiping process used by CCleaner. Serious wipers usually offer a US Military spec option that overwrites multiple times with different patterns. Also, I think I read somewhere that CCleaner only wipes unused space for files still listed in the Recycle Bin. But this doesn't make sense from what I've read about it putting all free space in one big file.
