Nevermind, i figured it out. If you want to adapt, you can use my code to add to the PHP to define the archive name as well as the folder names inside the archive:

function my_bdfgf_entry_filename ( $entry_filename, $entry_id, $uploaded_file ) {
	$entry = GFAPI::get_entry( $entry_id );	
	$foldername1 = rgar( $entry, 3 );
	$foldername2 = rgar( $entry, 29 );
	$foldername3 = rgar( $entry, 30 );
	
	// Dies ist der Name der Ordner im Archiv wobei '/' den Unterordner definiert.
	return  $foldername1 . '/' . $foldername3 . '_' . $foldername2 . '/' . basename( $uploaded_file );
}

add_filter( 'bdfgf_entry_filename', 'my_bdfgf_entry_filename', 10, 3 );

function my_bdfgf_download_filename( $filename, $form, $entry_id ) {
	$entry = GFAPI::get_entry( $entry_id );	
	$foldername1 = rgar( $entry, 3 );
	$foldername2 = rgar( $entry, 29 );
	$foldername3 = rgar( $entry, 30 );
	
	// Dies ist der Name des Archivs.
	return $foldername1 .  '_' . $foldername3 . '_' . $foldername2;
}

add_filter( 'bdfgf_download_filename', 'my_bdfgf_download_filename', 10, 3 );
