I received an email with an attached PAF file created on a MAC System 7.1 and LDS 1988 program, so I assume the PAF file is 2.11 (they COULD be an older PAF version). I saved the attachment to my Windows 98 sytem hard disk and it saved with a .dat extension. It will not open in FTW 6.0. FTW help menu states "If you are trying to open a PAF file from the Macintosh version of PAF, you must first save the PAF file in PAF's DOS format before attempting to open it in FTW". That statement I do not understand. Anyone can help?
