对于不为空的目录则要用递归删除看看下面的例子，虽然不是递归
String IMGDIRECTORY=application.getRealPath("APP_HOME/VEND_COMM/BBS_GROUP")+"\\"+String.valueOf(deleteStr1);
  File Filepath=new File(IMGDIRECTORY);
  if(Filepath.exists())
  {
  File filename = new File(IMGDIRECTORY);
      String[] fileString = filename.list();
  int filecount = fileString==null? 0:fileString.length;
  for(int i = 0; i < filecount ; ++ i)//ÁÐ³ögroupÄ¿Â¼ÖÐËùÓÐµÄÎÄ¼þºÍÄ¿Â¼
  {
  File FileDirectory = new File (IMGDIRECTORY+"\\"+fileString[i]);//ÁÐ³ögroupÏÂµÄÎÄ¼þºÍÄ¿Â¼Ãû
  //out.println(FileDirectory+"<br>");

  if(FileDirectory.isDirectory())//ÅÐ¶ÏgroupÏÂµÄÄ¿Â¼£¬¼´topicÄ¿Â¼
  {//Èç¹ûÊÇÄ¿Â¼
     String[] topicfileString = FileDirectory.list();//»ñµÃtopicÄ¿Â¼ÏÂµÄËùÓÐÎÄ¼þ
int topicfilecount = topicfileString==null? 0:topicfileString.length;
              for(int j = 0; j < topicfilecount ; ++ j)
  {
                 File topicdeletefile = new File(FileDirectory+"\\"+topicfileString[j]);//±£´æÒªÉ¾³ýµÄtopicÍ¼Æ¬ÎÄ¼þÃû;
                 if(topicdeletefile.isDirectory())
  {
                      String[] responsefileString = topicdeletefile.list();//»ñµÃresponseÄ¿Â¼ÏÂµÄËùÓÐÎÄ¼þ
          int responsefilecount = responsefileString==null? 0:responsefileString.length;
  for(int k = 0; k < responsefilecount ; ++ k)
  {
                         File responsedeletefile = new File(topicdeletefile+"\\"+responsefileString[k]);
responsedeletefile.delete();
  }
  }

topicdeletefile.delete();
  }   }

  File deletefile = new File(IMGDIRECTORY+"\\"+fileString[i]);//±£´æÒªÉ¾³ýµÄÎÄ¼þÃû;
  //out.println(deletefile);
  deletefile.delete();
  }
Filepath.delete();
  }
