    public static void main(String[] args) throws Exception {
        System.out.println("unzip start");
        long a = System.currentTimeMillis();
//        unZipFiles(new File("E:\\新建文件夹\\安全帽反光衣-尺寸一样.zip"), "E:\\a2\\");
        unzip("E:/新建文件夹/安全帽反光衣-尺寸一样.zip","E:/a3/");
        System.out.println("unzip end b=" + (System.currentTimeMillis() - a));
    }
}

在上面的代码中 

Files.size(file) 获取文件的大小，有没有像 entry.getCompressedSize();获取解压缩文件大小的
