Database files: Some TBK files use the JetDB format as JetForm database files. They hold structured data and work with software like Microsoft Access. Visit Microsoft Access for information.

Data and backup files: A few TBK files serve as takeoff software data files or work as backup files for applications such as The Bat!. More on backup recovery can be found at The Bat! Support.
