I didn't try Explorer specifically.  Since I was in a DOS box anyway,
I used rmdir/s to clean it out.  I'm sure using Explorer would have
worked too.

This is a timing problem.  By the time I can click on the folder to
delete it in Explorer, or by the time I can type "rmdir/s xx",
Copernic is long done reindexing the files, so there's no problem
nuking the directory then.  shutil.rmtree issues the rmdir at machine
