 public boolean deletefile(String path){ 
  boolean flag = false; 
  File file = new File(path); 
  if (!file.exists()) { 
   return false; 
  } 
  if (!file.isDirectory()) { 
   return false; 
  } 
  String[] str = file.list(); 
  for (int i = 0; i < str.length; i++) { 
   System.out.println("333:"+str[i]); 
   File fi = new File(path + "/" + str[i]); 
   if (path.endsWith(file.separator)) { 
    fi = new File(path + str[i]); 
   } else { 
    fi = new File(path + fi.separator + str[i]); 
   } 
   
   if(fi.exists()||fi.list().length==0){ 
    File myFilePath = new File(path+"/"+str[i]);    
    myFilePath.delete(); 
    } 
   if(fi.isDirectory())//如果文件假内还有 就继续调用本方法        
    {           
    deletefile(path+"/"+str[i]);       
    }else{
