When you know the filename, you can get the complete path like this:

\starttext

\ctxlua{tex.print(resolvers.find_file("texgyrepagella-regular.otf")) }

...

\stoptext

Your question is now answered but why do you need the complete path?

I want to modify an example from Patrick (Eigenen Fontloader erstellen) in his blog. I hope I will learn a little from this. Wolfgang
