|BEST PRACTICE: Supporting Directories|
Never copy supporting files, these should be in one or more centralised locations. Some types of files that would go in here are dialog graphics for the MSI's user interface and options and configuration header files for all (or some groups of) MSIs.
Assuming you are a member of a team working in a larger company, the following is an example of what you might wish to use as a search path for support files:
The contents of the "MAKEMSI_USER_FILES_PATH" environment variable is by default added to the list of paths searched for files. It should contain one or more semicolon delimitered direcory locations. You can also use the PPWIZARD "/IncludePath" switch any number of times on the invoking command line (possibly via the "MAKEMSI_MM" environment variable).
