Directories are created on-demand when files are created inside them.
The only case where Windows Installer will make an empty directory is
if you explicitly ask for one using the CreateFolder element. An empty
<Directory>, or in your case, a <Directory> with components that are
conditioned away, will not make an empty directory on disk.
So your code will do what you want.
