Copying files that don't exist already - Robocopy syntax? Or other?

[Robert]

I was told I could use robocopy to copy all the files from one drive to
another which aren't already there, that is, where there is no matching file
path and name. In other words, copy so no file is replaced. I have
installed robocopy (and some other stuff that came with it). Does anyone
know the syntax to do this? (Or have another suggestion?)

Run "robocopy /???" in a command shell.

I'm guessing you want to use the /XN parameter.

So you don't want newer versions of a file in the source folder to
overwrite older versions of a file in the destination folder? But then
why were the newer versions of the file created?
