Personal Ancestral File, often called PAF, was a popular MS-DOS program, and later a Windows program, for years. In fact, a Macintosh version was available for a while but was dropped years ago. Development of the Windows version was stopped in 2006. For details, see my earlier article published in the October 29, 2006 newsletter at http://goo.gl/8bh63. However, the program has remained available for download for the past seven years. FamilySearch even continued to offer support on PAF for anyone who had questions or problems with it. All that is now ending.
Beginning July 15, 2013, PAF will be retired and will no longer be available for download or support. Advances in technology, strong alternatives from third parties, and the need to focus on the latest FamilySearch initiatives have diminished the need for PAF as part of the FamilySearch offering.
