Hmmm...this is a slightly wimpy answer, but here's an alternate approach.
Just OPEN the source file before you try to open or destroy the destination
file.  If the files are the same then the Destroy or Open (for Write
permission) will fail.  This won't help you know when to display a very
specific message about not being able to replace a file with itself, but
you could display something more generic ('The file Blah is in use and
can't be replaced' or whatever).
