Update: CCleaner 2.17.853 - free disk space wiping
CCleaner 2.17.853 is now available.
The most interesting addition in this version is the ability to wipe free disk space.
There was already a secure deletion routine implemented in CCleaner, but until now, it was able to only wipe files. This meant that if you deleted a file the usual way and then remembered you wanted to wipe it, you were out of luck.
However, CCleaner 2.17.853 can wipe all free disk space on a partition (or more, there’s a new entry in Options->Settings). The way it does this is interesting and strange at the same time: it seems to create a huge file, taking up all your free disk space, and then it wipes it using the usual secure delete routing.
Some users reported problems with this new functionality, but I’m sure the developers will iron out any existing quirks for the next release.

I just spotted this option and i;m now using it. What benefit does this have on the Operating system’s performance? does it help Hard Drive functions?

Not really. It just allows you to wipe disk space that’s not used up by files.
Usually, software that implements wiping or secure deletion routines work with files not free disk space, so this is a very interesting feature. It doesn’t make your HDDs faster, though.

downloaded latest ccleaner, but the wipe of free space wont complete. left it on for 6 hours………

Mine has been running over 5 hours now. Sure would be nice to know whether to wait of kill it.

I suppose the run time depends on how large your hdd is, how much free space you have on it and also on how fragmented is that free disk space.

only C drive, which is 45 gig. i defrag regularly……once a week or so……….have read where this incompletion is not uncommon, but no answers given as to what to do, other than perhaps decompress the hard drive? i do know it is compressed
whole hard drive is only 52 gig……………
May 8th, 2009 at 8:35 pm
Hard drive is 223 GB and about half full, but CCleaner says it has completed 109,502.7 of 109,502.7MB, or 100% of the wipe free space, but remains at 97% completed. It has been that way for over 5 hours. (Running on XP Pro).

let wipe clean run on 41 gb of free space for 10 hours…….still would not complete
May 10th, 2009 at 9:44 pm
i decompressed C and it worked fine…………

if it’s running for several hours it may be due to hard disc errors. Did anyone check the event logs for disk related errors or have you ran chkdsk? I used the wipe clean feature [cclean v 2.19.901] that took about 10 min to complete with 24,397.4 MB of free space.
Winxp SP3 and latest patches as of 6/10/09, 2.8GHz P4.

Interesting. But I don’t understand why one have to choose which partitions in the CCleaner settings? It seems too fast to clean all those in one go when running it from right-clicking bin recycle bin. I also noticed a new right-click option on the drives in windows explorer; “Sweep free space”, which seem to behave like described here (make a big junk-file of the free space then wiping that).
However I got several virus warnings from Avira Antivir Personal. I hope those were false positives from the random patterns the free-space-sweeper makes.

WILL THE WIPE FREE SPACE DELETE MY SYSTEM RESTORE ENTRIES
SOME CLEANERS REMOVE YOUR SYSTEM RETORE …NOT GOOD

i used the wipe free space and my computer lost half i6ts memory on the c drive, as soon as i saw this i stopped it.
Whats the benefit of this wipe free space thing if it reduces memory.
July 16th, 2009 at 7:26 pm
That’s normal behaviour. It happens because CCleaner first creates a huge file and then wipes it using its secure delete routines.
If you had waited for it to finish you would have noticed that the previously “lost” disk space is back.

Does it just delete all the stuff then i get less stuff
such as i used up 15G out of 180G
then i use “Wipe Clean Space”
then i have 10g out of 180G
is it like that?

Thanks, I give this a try on a laptop that someone given me. I previously just use a free program called “file restoration” to perform Free space wiping on my computer. But, CCleaner seems easier to use for beginners.

I can see my disk space being reduced and the great thing is,i have only left it for 5 min and it is 30%.It reduced from 50gb to 25gb in 5 min.Wow i wonder where they save the file.I wanna go take a look
October 26th, 2009 at 10:35 am
ITS GOING DOWN!what if the file cannot be deleted does that mean i would have to stay with 0 free space forever?

rajamir wipe everyday and everytime u go to the bathroom!

So I had the same problem as everyone else. It wouldn’t budge past 97% when it was at 100% of cleaning out my drives. I had watched my 98.6 of 224GB drop to 31.7 at the lowest and was scared to hit cancel after I read this thread in fear of losing all of that memory.
GOOD NEWS is - It’s at 131GB out of 224GB nw! So it worked.. but apparently just didn’t finish! Wonder what I would have got if the thing completed itself! Either way - don’t be afraid to hit Cancel - thats my point. It gives you back the memory you’re afraid has been taken!

I canceled the “wipe free space” feature before it finished multiple times due to the rapid loss of my 600gb hdd.
I later found a file on my c drive of a staggering 200gb that was slowly growing.
I’m guessing my space loss and the creation of this file was due to CCleaner wiping my free space?
I’m hoping i can delete this file later haha
February 7th, 2010 at 1:13 pm
What is the name of the file?

Just check inside your drive, for example C. there is a file called a lot of strange letters and numbers, and look at its size
Mine is currently at 33 Gb. And thats a lot
