planets.c, do_setplanet

Find:

   if( !strcmp( arg2, "filename" ) )
   {
      DISPOSE( planet->filename );
      planet->filename = str_dup( argument );
      send_to_char( "Done.\r\n", ch );
      save_planet( planet );
      write_planet_list(  );
      return;
   }

Change to:

   if( !strcmp( arg2, "filename" ) )
   {
      PLANET_DATA *tplanet;

      if( !argument || argument[0] == '\0' )
      {
         send_to_char( "You must choose a file name.\r\n", ch );
         return;
      }
      for( tplanet = first_planet; tplanet; tplanet = tplanet->next )
      {
          if( !str_cmp( tplanet->filename, argument ) )
          {
              send_to_char( "A planet with that filename already exists!\r\n", ch );
              return;
          }
      }

      DISPOSE( planet->filename );
      planet->filename = str_dup( argument );
      send_to_char( "Done.\r\n", ch );
      save_planet( planet );
      write_planet_list(  );
      return;
   }

This will make sure that you can't set the filename to nothing, as well as making sure a planet with that filename doesn't already exist.
