xcopy command. Can’t find the right solution.

Hi,

I’m using XP and can’t seem to find the right set of parameters to satisfy what I’m trying to do.

I want to copy files, directories and sub-directories from a source to a destination. BUT if the file name already exists in the destination I don’t want to overwrite, I just want to write the files and directories that do not exist to the destination.

Right now I’m using “xcopy [source] [destination] /e /-y”. This works but I have to click No to overwrite on each file that already exists on the destination.

Any ideas would be cool. Thanks.
