How do I update a .pnl file

[mrbean]

I inherited some LabVIEW code and I was asked to update some default settings.  I believe this is stored in a .pnl file in this particular code block, but I have never worked with a .pnl.  This code was originally created in a fairly old version of LabVIEW then updated to labview 2009, then to 2017.  I have not been able to find any documentation on .pnl files.  Can someone elaborate on whether they have an official name so as to be able to get more information on them?  I'm just not sure how they are created/modified.  Any assistance would be appreciated.

Have you tried looking in the code for where the file is read for clues to it's structure?

You could also try opening the file with Notepad (assuming a Windows environment).

Of course always keep backups just in case.

Is it possible for you to skip updating the default settings until after updating the code to 2017? This way, you won't have to deal with a .pnl, which seems like a pretty obscure file extension.
