解压的时候，针对文件夹判断创建不存在的文件夹，对文件夹只创建，不进行解压..因为解压是针对文件的，不是文件夹，文件夹需要自己创建。 

测试方法：

public static void main(String[] args) throws IOException {  
        /** 
         * 压缩文件 
         */  
        File[] files = new File[]{new File("d:/English"),new File("d:/发放数据.xls"),new File("d:/中文名称.xls")};  
        File zip = new File("d:/压缩.zip");  
        ZipFiles(zip,"abc",files);  
          
        /** 
         * 解压文件 
         */  
        File zipFile = new File("d:/压缩.zip");  
        String path = "d:/zipfile/";  
        unZipFiles(zipFile, path);  
    }
