.FAMILYX File Extension

Chronoplex Software introduced the FAMILYX format in 2010 when it released My Family Tree. You can save your information to a FAMILYX file and then share it with other users or store it as a backup.

You can also protect FAMILYX files with a password by selecting File → Protect File . After protecting the file, the app sets it as a read-only version until you enter the correct password. If you want to encrypt the FAMILYX file with authenticated 256-bit AES encryption, select File → Save as and then choose My Family Tree Files (encrypted) from the "Save as" dropdown menu to save it as a .FAMILYXS file.

To open a .familyx file, you need compatible software that supports this file format.
