我的任务
分享ASP中文件如何读写???????
有哪位老鸟给我讲解一下用ASP程序处理文件的读写及一些通常的处理的方法及代码，就好代码上能有注解此句代码的意思，我给一百分，如果分不够我可以再给，希望老鸟们别说我黑，谁叫我是一个菜鸟呢！！

FileSystemObject
示例代码
上一页
--------------------------------------------------------------------------------
在本节描述的示例代码，提供真实的例子来示范在 FileSystemObject 对象模式中可用的许多功能。该代码显示了如何一起使用对象模式的所有功能，以及如何在您自己的代码中有效地使用这些功能。
请注意，由于该代码是极一般的，所以要使该代码能够真正在您的机器上运行，可能需要一些其他代码和小小的变更。这些改变之所以必要，是因为在 Active Server Pages 和 Windows Scripting Host 之间，为输入和输出给用户采用了不同的方法。
要在 Active Server Pages 上运行该代码，则采取以下步骤：
创建一个标准的 Web 页，后缀名为 .asp。
把下面的示例代码复制到 <BODY>...</BODY> 标记之间的文件中。
把所有代码封装到 <%...%> 标记内。
把 Option Explicit 语句从当前位置移动到 HTML 页的最顶部，甚至在 <HTML> 开始标记前。
把 <%...%> 标记放置在 Option Explicit 语句周围，以保证它在服务器端运行。
把下面的代码添加到示例代码末尾：
Sub Print(x)
Response.Write "<PRE><FONT face="宋体"" SIZE=""1"">"
Response.Write x
Response.Write "</FONT></PRE>"
End Sub
Main
前面的代码增加一个将在服务器端运行，但在客户端显示结果的打印过程。要在 Windows Scripting Host 上运行该代码，则把下面的代码添加到示例代码的末尾：
Sub Print(x)
WScript.Echo x
End Sub
Main
下面就是示例代码：

Option Explicit
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
'
' 对于代码质量：
'
' 1) 下面的代码有许多字符串操作，用"&"运算符来把短字符串连接在一起。由于
' 字符串连接是费时的，所以这是一种低效率的写代码方法。无论如何，它是
' 一种非常好维护的写代码方法，并且在这儿使用了这种方法，因为该程序执行
' 大量的磁盘操作，而磁盘操作比连接字符串所需的内存操作要慢得多。
' 记住这是示范代码，而不是产品代码。
'
' 2) 使用了 "Option Explicit"，因为访问声明过的变量，比访问未声明的变量要
' 稍微快一些。它还能阻止在代码中发生错误，例如，把 DriveTypeCDROM 误拼
' 成了 DriveTypeCDORM 。
'
' 3) 为了使代码更可读，该代码中没有错误处理。虽然采取了防范措施，来保证代码
' 在普通情况下没有错误，但文件系统是不可预知的。在产品代码中，使用
' On Error Resume Next 和 Err 对象来捕获可能发生的错误。

'
' 对于代码质量：
'
' 1) 下面的代码有许多字符串操作，用"&"运算符来把短字符串连接在一起。由于
' 字符串连接是费时的，所以这是一种低效率的写代码方法。无论如何，它是
' 一种非常好维护的写代码方法，并且在这儿使用了这种方法，因为该程序执行
' 大量的磁盘操作，而磁盘操作比连接字符串所需的内存操作要慢得多。
' 记住这是示范代码，而不是产品代码。
'
' 2) 使用了 "Option Explicit"，因为访问声明过的变量，比访问未声明的变量要
' 稍微快一些。它还能阻止在代码中发生错误，例如，把 DriveTypeCDROM 误拼
' 成了 DriveTypeCDORM 。
'
' 3) 为了使代码更可读，该代码中没有错误处理。虽然采取了防范措施，来保证代码
' 在普通情况下没有错误，但文件系统是不可预知的。在产品代码中，使用
' On Error Resume Next 和 Err 对象来捕获可能发生的错误。

很多书上就有处理文件的示例呀。应该不难的吧。

就是用fso啦。可以参考微软的文档。msdn或者vbscript参考(VBSCRIP5.CHM)或者jscript参考(JSCRIPT5.CHM)

这是我自己写的几个函数你可以看看，其它fso操作很简单的
