The following might be useful in this context. It's a batch file
I call MVN.BAT, which moves files which are "new" only, as
in files that don't exist in the destination directory. In other
words, it won't overwrite files.

You may be able to modify it to provide prompt-on-replace
capability using COPY, XCOPY or REPLACE (and call it
something appropriate, of course) ...

>      * find, create, or move levels of directories quickly
>      * easily customize default options

>      What's more, to get all these features, you don't need to change or
