Just fyi, Copy File() does not appear to overwrite. If the destination file already exists the log will show a zero instead. There also does not appear to be any switch possible (e.g. 1 = overwrite, 0 = no overwrite).
So I'm resorting to: Delete File() then Copy File() for cases where I want it to overwrite an existing destination file.
Just passing this along in case it help others. I do appreciate these relatively new file utilities, they come in handy for sure. DJ
