The File Type node () contains settings for defining a file type with filename extensions. Such user-defined file types can be used in File Import form objects or as arguments to methods that open file browsers. You can also create new file types in the Settings window for File Import form objects by clicking the Create New File Type and Use It button ().

The Settings window contains the following section.

In the Description field, enter a suitable description of the file type.

In the table under Filename extensions, add allowed filename extensions for this file type. A new row appears when you have typed a filename extension on the row above. For a filename extension ext, you can enter it as ext, .ext, or *.ext; regardless of the input format, the filename extensions will appear as *.ext within parentheses and separated by semicolons in the file types lists.

Use the Move Up (), Move Down (), and Delete () toolbar buttons to organize and remove filename extensions from the list.
