A TBK file may also be a backup of a database text (.DBT) file created by dBASE database-managing software and IDE. It contains HTML-formatted text for memo fields in a database (.DBF or .DB2 file). When a user modifies the structure of a database that points to a DBT file storing memo text, dBASE automatically creates the TBK file to back up and restore the DBT file if it becomes corrupt.

More Information

dBASE is a Windows program that offers various database-related capabilities, including database management and tools for building and compiling programs. While dBASE databases can store a large amount of data, they may point to external files that separately store memo information to reduce their size.

For example, a DBF database that contains memo fields points to the location of a DBT file that stores the information for the memo fields. When dBASE loads the database, the software also loads the memo text from the DBT file.

If you modify the structure of a DBF or DB2 file via the MODIFY STRUCTURE command, dBASE automatically creates a backup file of the database (saves it as a .DBK file) and original memo text in the DBT file and saves it with the .tbk file extension. dBASE then creates a new table with the .dbf file extension and a new memo text file with the .dbt file extension to store the modified table structure and related memo text. After you finish adjusting the structure, dBASE moves the content from the TBK backup file to the new DBT database file and removes the TBK file.

NOTE: dBASE stands for "dataBased Intelligence."

How to open a TBK file

You can open a TBK file with dBASE in Windows. Typically, you will not open TBK files since the program automatically creates, loads, and removes TBK files.

You can also open TBK files with a plain text or source code editor. Remember, that incorrectly editing the TBK file may corrupt it.
