|robocopy c:\Sourcepath c:\Destpath /E /XC /XN /XO|
|:: /E makes Robocopy recursively copy subdirectories, including empty ones.|
|:: /XC excludes existing files with the same timestamp, but different file sizes. Robocopy normally overwrites those.|
|:: /XN excludes existing files newer than the copy in the source directory. Robocopy normally overwrites those.|
|:: /XO excludes existing files older than the copy in the source directory. Robocopy normally overwrites those.|
|:: With the Changed, Older, and Newer classes excluded, Robocopy will exclude files existing in the destination directory.|

Wouldn't it be simpler less stupid to have a special swith to exclude existing files instead of adding tree different ones to do the same job?

robocopy is a syncronization utility. That means that not copying files that are different would be strange. In that context, not comparing files at all is the weird edge case. The ability to turn off each type of difference check one at a time is the more useful scenario.
(I say that having come here looking for a way to turn off all the checks in one go)
