[David Masterson]

Remember to cover the basics, that is, what you expected to happen and
what in fact did happen.  You don't know how to make a good report?  See

     https://orgmode.org/manual/Feedback.html#Feedback

Your bug report will be posted to the Org mailing list.
------------------------------------------------------------------------

The documentation page for "4.4 External Links" could provide the
answers to following questions:

1. What "file types" are supported by link type "file"?

2. If #1 depends on some org variable settings, can you mention what
variables control the answer to #1?
