The three files upload inputs will be presented if you are using the theme that do not have any import filed predefined.
Demo content XML file needs to be uploaded as first file is important, for the real demo import.
The second one is not that much important. however for widgets import you will be asked for a WIE or JSON file. With the help of this you can create a file Widget Importer & Exporter plugin.
The third option is also not mandatory. thus the customizer settings will be imported, select the DAT file that can be easily generated from Customizer Export/Import plugin (from the same theme if and only if the export file was created than only the customizer settings will be imported.).
