Each Directory/@Id value is also a property that is the full path to that
directory. If you don't supply the path for any one of those properties, then
Windows Installer will create them based on the @Name values and the relative
positions of the directories. That is what allows <Directory Id="Foo"
Name="Bar"><Directory Id="ProgramFilesFolder" Name="FooBar"><Directory Id="Bar"
Name="My Folder"/></Directory></Directory> to make Bar = "C:\Program Files
(x86)\My Folder" without any consideration of what the value of Foo is.
If you need to build a path yourself out of provided properties, you will need
to build your directory's value by combining the other values. If you know the
entire path you are trying to build, do it by setting the property before
CostInitialize. If all you know is the subfolder's name and you need Windows
Installer to calculate your parent's directory, you will need to create a type
51 action scheduled after CostFinalize.
