Softdisk Family Tree

The Family Tree program from Softdisk Publishing (some versions were called "Enhanced Family Tree") appeared in three major versions, and a number of minor revisions. Some were published on issues of the diskmagazine Big Blue Disk / On Disk Monthly / Softdisk PC (for PC/MS-DOS), while other versions were released as standalone programs in various places such as an online download store. Later versions could import and export GEDCOM files, but the native data storage was in a binary format specific to the program. Like the program itself, the file format had three major versions (later program versions could import the data formats of the earlier ones).

A "file" was actually stored in four files, with extensions .FPD, .FMD, .FIX, and .FCM, for person data, marriage data, index data, and comment data respectively. The filename before the extension was the same for all the files connected to a particular data set.

Family Tree 2 (Enhanced Family Tree
