Yes, I did read that and was shocked. Is everything in python that
iffy? I believe there was a traceback, I'll have to look again when I
am back at work tomorrow.
The problem with that concept of "modifying the distribution as you
go" is that those changes must be moved to every system where your
program will run, and whenever python is updated, you have to remember
to save the changes before uninstalling the current version. The
shutils in the new python dist may not be compatible with your old
changes and may require more work. Bad idea. How did that ever get
approved to be in the standard distribution?

I had started doing xcopy, but it became unreliable but I don't know
why yet, so I decided to try shutil.
I am doing the file copies in a thread, but that shouldn't matter.
I will look at your other file copy suggestions.

Thansk for both replies
