With the /OP syntax. Which leads to the need for a backslash. Bill Gates learned on the PDP-11 and it's still plaguing us today. Anyway, thanks for the example.

Under a Windows system the built in command, copy, is a pile of crap
and xcopy is not much fun; you need to screw with it at the command
prompt to find the exact usage.
Uh... well, not because you don't know the command syntax it becomes a
pile of crap...
The formal way to copy files on the 'OS level' is by way of a system
call. I believe under Windows NT, this would be the CopyFile family;
using that through cctypes doesn't sound like fun.
It's as simple as this:
from ctypes import windll
CopyFile = windll.kernel32.CopyFileA
CopyFile(d:\\temp\\old.txt, d:\\temp\\new.txt, True)

Have I missed something? What's wrong with shutil?
shutil.copyfile(source, destination) seems to work for me, even on
Windows.

What's wrong with shutil? There's nothing wrong with shutil, but CopyFile and friends have some additional features (correct handling of alternate data streams, progress callback, reduced disk fragmentation...) that some people may be interested in.

This simple question would surely have been asked many times before.
Not to impose on anyone's patience I expect it can be answered between
two sips of coffee.
Thanks very much
Did you take a look at the shutil-module?

No, I didn't. There's a number of modules I know by name only and
shutils was one of them. A quick peek confirmed that it is exactly what
I am looking for. Thank you very much for the advice.
