Open FBK File
FBK extension files have various applications, some of them described below:
Family Tree Maker for Windows
In this case, the FBK file is a compressed backup of a family tree file, specifically backup of FTW files created with Family Tree Maker for Windows.
The FBK file can be created as a backup file, in case the original family tree file is corrupted or deleted.
This being the case, the FTW file can be restored by selecting the FBK file in 'File ? Restore from backup' within Family Tree Maker.
As an important note, Family Tree Maker for Windows uses the FBK file extension, while Family Tree Maker for DOS saves backups as FBC files.
AutoCAD Civil 3D
In this section, the FBK file is a file used by AutoCAD Civil 3D.
AutoCAD Civil 3D is a BIM (Building Information Modeling) type program used for the design and documentation of civil engineering.
In this case, the FBK file is saved in a plain text format and stores observed point data, however this file can be imported into a drawing.
FBK files can be created from raw survey files in AutoCAD Civil 3D.
Microsoft Dynamics NAV
In the latter case, the FBK file is a backup copy of a database created with Microsoft Dynamics NAV.
Microsoft Dynamics NAV (Formerly Microsoft Navisio, now known as Dynamics 365 Bussiness Central) is an Enterprise Resource Planning (ERP) application from Microsoft.
This software is intended to assist with finance, manufacturing, customer relationship management, supply chains, analytics, and e-commerce for small and medium-sized businesses and local affiliates of large international groups.
Such an FBK file contains financial data used for business analysis and management, and can be used to restore the data if the main database file, or FDB format, becomes corrupted or deleted.
