Deleting files

  StellaArtois63 23:46 16 Nov 2005

I have read recently that when we delete anything from the PC using "recycle bin", it does not actually remove the file from the PC it just tells the computer not to use it and sits idle on the hard drive. Then if you were to sell your PC, anyone with the know how could see all your previous actions done on the PC.
If this is correct can anyone advise me on a good, free file eraser, and what dangers I could come up against using it. Many thanks.

Unless your doing dodgy stuff on your computer I wouldn't worry. click here clears out junk from the hard disk.

When selling the computer do a reformat and re install the OS and defrag the hard disk a few times. Anyone wanting to recover the data off the hdd would have to pay a fortune as data recovery is INCREDIBLY expensive.

When you delete something, your telling the computer it can save something else to the space that the deleted file occupies on the hard disk. Therefore that space may be overwritten with another file soon after anyway.

It's not quite correct to say it sits there idle on the hard drive.

It's true the file is not erased. But what happens is that the space it occupies is made available for re-use. So eventually it gets written over by new files - either in part or totally.

So someone might find some of your deleted files, but not all of them by a long way.

The advice to reformat and re-install the OS when selling is good - and all that's needed in normal circumstances.

I thank you all for your replies it makes interesting reading. I think I will just carry on as normal but its worth thinking about if I decide to replace this one. Having said that I dont think I have anything to hide and my brother in law has his eyes on this PC. Again thanks for all your help.
