It will work only during first install, as Rob most likely knows. During
repair, feature change, and uninstall the SourceDir location is (IIRC) the
installer directory of the cached MSI file.
It's not good design to rely on external files in the same location as the
MSI. There are too many failure points, as just mentioned. Also, Group
Policy and web installs don't work, and a simple mistake in staging the MSI
file and the external file to the install source changes the install logic,
and that probably can't be corrected later. If there is really a need for
an optional external file it would be better to have it in the binary table
or have the data as properties, and give customers a tool to add the file
(or the data) if necessary. Or change the design.
