How to include a subfolder in my compiled GUI package?

I have a GUI that I made with Guide. There are multiple sub-folders containing input files & etc. that my gui uses to operate. My application uses many files and I can't just take the input txt files out of their folder and compile everything together. Does anyone know how to compile/include a sub-folder with/in the compiled package and how to call that sub-folder? I know that path-management is different in compiled applications. Is there a smart way to solve this issue?

your comments are appreciated
