Family Tree Maker is genealogy software for Microsoft Windows and Apple Mac OS X (macOS).
The ftb file stores a Family Tree Maker family tree and related genealogy information. It serves as the program's native genealogy data format in versions that use this extension.
The format is primarily associated with older Family Tree Maker releases. Newer releases may use different native file extensions, so compatibility can depend on the version that created the file.
Open the ftb file in a compatible version of Family Tree Maker for Microsoft Windows or Apple macOS. Use the program's Open command.
Family Tree Maker versions for macOS may not support every Windows-created file directly. If the file does not open, use the Windows version that created it or a compatible release.
Open the ftb file in a compatible version of Family Tree Maker, then export the family tree as a GEDCOM file. GEDCOM is intended for transferring genealogical data to other genealogy programs.
