The first lines of a CFTW gedcom export file look like this for all versions from 2.00 to 2.29: 0 HEAD 1 SOUR CFTREE 2 VERS CFTREE 2.0 Windows Will it not be better to write the exact version number - for example: "2 VERS CFTREE 2.29 Windows"? There are a lot of changes made from version 2.00 to 2.29 - and some of them certainly affects the gedcom export file - the date change in 2.08 for example. Therefore it might be of some importance for the receiver of a gedcom file to know exactly which version made the file. Of course it is easy to fix this line in a text editor just after you have made the file - but a lot of people are not familiar with that - and might experience problems with opening large files.That is the reason the version line is in the gedcom file - isn't it?
