Two applications use the FBK file type. These are Microsoft Dynamics and Ancestry.com Family Tree Maker. FBK files use a .fbk file name extension. FBK files are backup files. To convert an FBK backup file, restore the file using the application that created it. In the case of Microsoft Dynamics, the FBK file type is a backup file of the primary database. The FBK file may be used to restore the primary database using Microsoft Dynamics Navision, newly named NAV. For Family Tree Maker, the file is easily restored using the application interface.
