When you enter export specifications and use the Save As command from the File menu, you are to saving the contents of the Export window. The saved file is a Batch Export file containing one export transaction. It has a .exp file name extension. A Batch Export file also can be created using any ASCII text editor. You can preview how an export specification would look as a batch file by clicking on Batch Export Commands from the View menu.
Batch Export is particularly useful when you have a number of similar tables to export, or when you export the same table(s) on a regular basis. Once you have created a Batch Export file you can use it over and over, with or without modification.
