If a file's definition needs to be changed and meaningful data exists, follow these steps to convert the file. This method does not create an executable file.

Modify the data file definition as desired (add fields or keys, etc.).


With the modified file highlighted in the DCT Explorer, press the button to load the data file in the Database Browser.

A dialog appears, giving you different options to convert the table..


Select an option, and press the OK button to convert the file.

The conversion process is now complete!
