我写的代码如下，但始终的不到F.SIZE的值
1<html>
2<head>
3<script language="VBScript">
4sub ok_OnClick
5ShowFolderSize document.mainform.mefile.value
6end sub
7
8sub ShowFolderSize(filespec)
9Dim fs, f, s
10Set fs = CreateObject("Scripting.FileSystemObject")
11Set f = fs.GetFile(filespec)
12s = UCase(f.Name) & " 大小为 " & f.size & " 字节。"
13MsgBox s, 0, "文件夹大小信息"
14End sub
15
16</script>
17<title>Untitled Document</title>
18<meta content="text/html; charset=utf-8" http-equiv="Content-Type"/>
19</head>
20<body>
21<form enctype="multipart/form-data" method="post" name="mainform" onsubmit="return geturl()">
22<font color="#E85E35">图片：</font><input name="mefile" size="22" type="file"/>
23<input name="ok" type="submit" value="确定"/>
24</form>
25</body>

在客户端访问文件系统是一种不安全的做法..
用于internet的站点不要把逻辑建立在客户对你充分信任的前提下
---------------------------------------------------------------
用asp组件，Scripting.FileSystemObject。只要客户端的安全设置允许你访问他的文件系统就可以的。
