For a steel, aluminum or Ti dropout just file it off with a flat file and you're done. It doesn't have any structural purpose. I'm not sure what to do with a carbon dropout. Maybe applying a layer of household epoxy to the filed away area would be smart. Hopefully the makers of full carbon forks aren't molding those stupid things in. They should only be on bottom end bikes bought by casual bike riders.
