Hello Sarah -- thank you so much for taking the time to help me out. If I
wasn't going to distribute my standalone program to others, your suggestion
would work. But I do intend to distribute it, so the QT files must be an
internal part of the application package.

Thus, my problem was not finding the absolute path to a QT file on my hard
disk from the standalone application. My problem was getting the standalone
builder to include the QT files in the standalone package, and then getting
the standalone application to point to the files in the application package
and play them.

However, thanks to your suggestion, I was able to determine the solution to
my problem. When I put the QT files in the same folder as the stack file and
I added the files in the Copy Files in the Standalone Application Settings
and located the player files in the Inspector, the file path was relative to
the stack file, the QT files were not included in the standalone package,
and (of course) the players in the standalone application didn't play. On
the other hand, when I put the QT files in another folder, the file path in
the Copy Files and the player files in the Inspector were absolute, the
files were included in the standalone package, and it worked like a charm.
Your suggestion to locate the file path using a button (in the standalone
application) resulted in an absolute file path -- which led me to try out
other locations for the QT files that resulted in absolute file paths in the
Copy Files and player Inspector. Thank you.

I sure wish Revolution would prepare a tutorial on the use of external
files.

Bob
