I know how to use xCopy, but what is the switch to not overwrite file within that command.

It actually gets a bit more complicated, but you can use the /l switch to list the files to be copied and then run a for...next loop to only copy the file names that don't exist.

A better option than xCopy might be Robocopy [technet.microsoft.com], but it may not be available natively on your platform.
