| Using the SAS Import and Export Wizards |
From the main window of the Import and Export Wizards, you can also access the External File Interface (EFI). This is a point-and-click interface that you can use to read and write data in a file type that is not known to the Import and Export Wizards. For example, you could use the EFI to transfer data from a SAS data set to a file format that is proprietary for your company.
For detailed information about using the EFI, click the Help button.
As shown in the following display, you can access the EFI by opening the Import Wizard and selecting the User-defined formats check box.
