I am trying to import a PAF file onto a Gramps file on a Windows 8.1 program.  How do I get a Gedcom or XML to change over the file from an XP program PAF file?
You create a GEDCOM file in PAF by choosing export in the file menu, leave all the options as they are, and choose a file name to write to. You can then create a new database in Gramps, and import the file that you just made in PAF.

I am assuming that you still have a copy of PAF in your Windows 8.1. If not, I can put a copy on Dropbox or some other place where you can download it. You can also use the free version of Ancestral Quest, if you want.
