By default, the Folder property is False. If the Folder property is True, the FileType' attributes are applied only for folders, and if the Folder is False the FileType' attributes are applied only for files. The Apply method applies the changes to the current list.  Use the BrowseFolderPath property to specify the path to the browsed folder.

With ExFileView1.FileTypes
    With .Add("*")

    End With
    .Apply
End With
