asp下利用xml打包网站文件

这个方法可以把整个文件夹打包到xml文件中，把这个xml文件文件和解包文件放在一起后，运行解包文件就可以把原来的文件释放出来，这样我们就可以把网站打包上传到虚拟主机，再运行解包文件就可以了。我在本地测试之选择了少部分文件，不知在文件很多的情况执行效率如何。
    其实实现的思路也很简单，主要利用的是xml文件可以存放二进制数据的原理。有兴趣的朋友可以下载下面的附件研究下！！
解包文件


代码如下:

<%@LANGUAGE="VBSCRIPT" CODEPAGE="65001"%>
<% Option Explicit %>
<% On Error Resume Next %>
<% Response.Charset="UTF-8" %>
<% Server.ScriptTimeout=99999999 %>
