  • Chris Kang thinks this is interesting:

In the previous chapter, you saw that to define which directories to copy your files into, you use Directory elements. These take an Id value and, if it's a new directory that you're creating, a Name attribute. You can use any of the built-in IDs to reference one of the common Windows directories. For example, suppose we wanted to add an XML configuration file for our software to the %PROGRAMDATA% folder. We'd add a reference to it using the built-in CommonAppDataFolder property as Directory Id

Note

"Nate" attribute value defines the name of the directory to be created.
