Ahh, OK. Are you leaving your old IndexReader open against the index while your new IndexWriter is creating the new index? Are you running on Windows?
If so, then this behavior makes sense: the old IndexReader will prevent deletion of all files it is using (which is all files in the index when the reader was first opened). Only when you re-open the IndexReader will those files be deletable. However, they will not actually be deleted until you next open a writer. You could simply open then close a new IndexWriter with create=false, after you've closed the old reader. This will "touch" the index and delete the files that are now deletable, which should be all files for your old index.
