How can I ready a m file form a exe program?

I'm writing a program that solve some functions and I'd like to share it as a executable exe file, but the function to be solved need to be created by the user in a .m file. So can I create and read the function file (.m) externally and then read it from the exe program?

I tried Govind's method, but still can't read a .m file that is not grouped into the standalone exe app.

Where UFF is the .m file

When I try to add the path, I get this.
