File: String;
The File property determines the path and the name of the file DBF of the table, in which data is exported.
Executing the example requires that the repository contains an ETL task with the ETL identifier and the Base_1.Dbf database file in the root of the C disk.

After executing the example the Export to Dbase object is created in the ETL task. This data consumer exports data to a database file. During connection the dBASE IV drivers are used.
