Depends whether the deleted file is still in the Recycle Bin: if it is,Scott said:This might be another mad question, but what is the best way of
ensuring that deleted files cannot be recovered later? I realise the
sensible approach would be to 'shred' them in the first place (an
option in Norton Utilities) but what would you guys recommend to carry
out a clean-up later? I assume a back-up, reformat and restore would
work but I was wondering if anyone could recommend reliable software
that would avoid going to this extreme.
and you restore it, I _think_ it isn't _copied_ from where it was, but
just marked as undeleted again, at which point shredding could be done.
I suspect the more deep recovery utilities (like the Shadow Explorer
that Graham mentioned?) _do_ reassemble a _copy_, thus leaving the
original (though fragmented), so using them and then shredding wouldn't
work - the original would still be there.
I think once you've got beyond it being recoverable from the ressicle
bin, you have to overwrite all the "free" space on your drive (and purge
the page file); this is less drastic than a complete reformat, and there
are utilities that do it. But as others have said, there are still nooks
and crannies (I hadn't even thought of reallocated sectors!) where
fragments of your file - or the whole file if it's something small like
a password, rather than something large like pr0n - could remain.
It all depends on what your _reason_ for wanting to do this is - and I
understand you may not want to say (-:!
