Hmmm. I don't do windows, so I am no help there. However, I am
somewhat familiar with the unix environment, and the "cp" command under
unix will copy over the existing file, without an error, warning, or
prompt. If you want that behavior, you have to pass it a command line
argument (usually -i). Some people may alias cp to get that behavior in
their interactive shells (e.g., alias cp="cp -i"), but it is definitely
not the default, and I agree that copy_file() call should not force the
file to be gone before doing to copy.
