Secure deletion of files.CCleaner.

  john bunyan 22:27 06 Jul 2010

I have once used CCleaner to "Wipe free space" in the advanced option. It took quite a long time. I have noticed, in the "Options", "Settings" you can set a secure deletion for 1 pass, 3 passes, 7 passes or even "Gutman" at 35 passes. This seems a very good free facilty if needed, but is it too long winded and do other programmes work better?
This may be worht a thought ig you were selling or giving the PC to someone else, or would the data still be recoverable? eg Emptied recycle bin after deeting data files.

Thanks, I know it looks like a double thread, but this question is a bit more in that I hoped others would comment on the efficacy of CCleaned in this role vs other secure delete programmes.

I have my ccleaner set at Gutman" at 35 passes this saves me having to move files to eraser for safe deleting.

If you have top secret classified files on your PC then Gutmann is probably the best way to permanently delete the files without destroying the drive.

For normal mortals then anything more than 3 times overwrite with random data is just a waste of time.

Thanks for replies. I note them for future reference. CCleaner seems better than ever.

I use the pc for managing finance the more secure the better. even for deleted files.

so do I, a firewall an single pass deletion is fine.

All my financial records are held in a Truecrypt partition. This partition is encrypted with 256 bit AES-Twofish-Serpent using a 12 digit seemingly password.

insert the word "random" in the last line...

This topic is riddled with myths, urban legends, and misinformation. The authors of CCleaner either don't know what they are doing or intentionally perpetuate these bad ideas for marketing purposes. The article <a href="click here">"Shred files and wipe disks"</a> should set the story straight. If you are giving a PC to someone else, it may be possible to recover useful information if you simply delete files, empty the recycle bin, and wipe the free space because some information will be slack space (very small, not usually significant), swap memory, hibernation file, Windows registry, and application (e.g., Firefox) registries. Also, multiple passes are completely useless and redundant.

Is this spam on a relatively older thread?
