   uint64_t child = truxton_child_file_create( truxton );

   char id[40];

   truxton_file_get_id( parent_file, id, sizeof(id) );
   truxton_child_file_set_parent_id( child, id );
   truxton_child_file_set_type( child, Type_ASCII_Text );
   truxton_child_file_set_name( child, "Hi.txt" );

   uint64_t now = truxton_time_now();
