Robocopy switch question about /xn and /xo

Last Modified: 2012-05-09
We use robocopy to sync files back and forth between two file servers running on different operating systems.  The robocopy options I'm using are:
/E /XO /XN /X /R:1 /W:10

So, the /xo and /xn switches are supposed to exclude "old" files and "new" files, however in the output , I still see files being copied that are showing as "new file".  My hope is that these files are actually "changed" files (since the exclude change switch is not being used here).  Can anyone confirm this?

What we're trying to accomplish is a copy in which only new or updated files/folders are copied and no others.  This is highly critical as the target file server is being used by several hundred people and the last thing we want to do is make a mistake in our switches causing some files or parts of files to be overwritten by anything other than a file that is updated or a completely new file.  Thank you.
