I had sorta gathered that, but was unsure about the details and
consequences. If the original file was erased, presumably those Shadow
Copies of differences in previous changes would be unresurrectable in
the form of a previous version of the file, but would they continue to
exist in a form that could still potentially be recovered for the
information provided in the changes to the original file?
I really have no super-secret files of concern here, but the issue may
be of more real importance to others who do. The question(s) occurred to
me in regard to a document file in which I keep a list of passwords. I
keep this file encrypted in the form of an executable file that requires
a password to extract the document. When I need to make a change to the
list of passwords, I execute the encrypted file to extract the
unencrypted document, then I make the changes to it, erase the original
executable file, re-encrypt the changed document into a new encrypted
executable file, and finally erase the unencrypted document itself.
During this process, I presume shadow copies are being made of the
unencrypted document when I change it, and I'd wondered if those
newly-entered passwords continue to live on in the form of "shadow
copies." Now, no one is going to go to great lengths to uncover my
passwords, but there are certainly many people with much more sensitive
information than I to whom these issues must be of some concern.
Anyway, I see Michael has done some investigation and dug up some links,
which I now need to find some time to study through to see if my
questions/concerns (such as they are) are addressed therein.
