Jason,

Both source directories contain many files with distinct
names, but there are many duplicates. I want to combine
the distinct files and, of the dups, keep the newer one.

Does "xcopy" still exists on W10 ? If so :

/D copy only newer files

(use "xcopy /?" to get the whole list)

Nice one, I forgot about it, and it is still in Windows 10 too.

Yes, often simple is better. I got a headache from looking at robocopy
and then just used 'xcopy /D' (with some other 'switches' thrown in) for
making incremental 'backup' (actually an archive copy) of a source tree.

OTOH, if you're familiar with robocopy, xcopy might look 'weird'.
