What is a DDX File Type?
A DDM, DDD, and DDX file will be created for each table you create in Alpha Five. These are the data dictionary for a DBF file. The dictionary stores recorded utilities settings, layouts and queries. Referred by Alpha Five to extend the capabilities of the DBF file. The DDX files must be kept with DDD and DDM Data Dictionary so that they can find all the elements and their parts.
Alpha Five became Alpha Anywhere in 2013.
What is a Default DDX File Name?
When a table is created, the DDX file will be created with the same name as your table.
