My need is to find a kind of master file for a program called Ancestry Quest 12.1, and it is *.aq This is similar to the older *.aft file used by Ancestral Family Tree. Also, the universally posted to the internet, *.ged file. It seems that a search of found files can be conducted, but how can a unique search for a unique file extension be done; especially if the file extension is not on the list of file types that RMF allows the user to choose from?
