I backed up a major genealogy file when I was using PAF 4.0. I no longer have that computer which was running PAF. Is there any way to download a copy of PAF (4.0, 5.0, or 5.2) so that I can open this back-up file? I need to access my data by converting the PAF file to a modern format. I have tried using Ancestral Quest to open this file, but this newer program cannot directly expand a paf .bak file. I have also tried FreeFileViewer, which does open a paf .bak file, but only unreadable code is shown.
