You can also call deleteUnusedFiles(), and all unreferenced files will be deleted either. Make sure to set the index DeletionPolicy to KeepOnlyLastCommit (which is the default), before you do that. That's relevant though if you've built the index using either 3x or 4.0 code.
If not, you can achieve the same goal by, say, add a document, commit, delete the document and commit again. The first commit will delete the unused files. Perhaps if you simply do new IndexWriter().close() it will delete the unused files as well, but I'm not sure.
