I've recently had to copy a bunch of files over two Windows Servers and was pleasantly surprised by robocopy's (basically Windows' rsync) solution to this dilemma: the first two parameters always only refer to directories, and then you can list specific files starting with the third parameter.

This way there can be no confusion whether you're copying the contents of a directory or the whole directory, and you can't create a duplicated directory within your destination by mistake.
