    That's not quite what I want. I usually want to just copy
files that don't already exist in the redundant backup. That
was part of the reason for the script: So that I can send 18
missing photos to the redundant photo folder without also
copying over the other 1,200.

   For me, personally, life is too short for command line. I write
scripts so that next time I do the same thing it will be effortless.
But I know that some people prefer commandline. I was just putting
it out there. Script is vastly more flexible and easier once the
script is written. But not everyone wants to learn scripting.

   No. I don't know what it is. I'm running as admin with UAC
and LUA disabled. These are files copied to data partitions.
In fact, my main data partitions are formatted FAT32 to avoid
such complications. But I've found repeatedly, when dropping
a folder into a data partition that already has that folder, I get
no popup asking whether I want to overwrite. Then I check the
existing folder and the new files are not there. So I now delete
the existing folder first, then drop the new folder onto the window.
