Setting output file name
This step of the wizard allows you to specify absolute path and name of the output file to save the table data into.
The file must be accessible to the server and the name must be specified from the viewpoint of the server. Note that the file will be written directly by the server, not by the client application. Therefore, it must reside on or be accessible to the database server machine, not the client.
