我已经安装了IIS7，并在以下位置拥有简单的网站:

C:/inetpub/wwwroot/testsite 的中文翻译为：

我可以将文件复制到那里，但是我无法编辑它们。

• I can open them but cannot save them back
• the files themselves are not write-protected
• the folder itself ("testsite") IS write protected, so I took the write-protection off (right-click, properties, uncheck read-only, continue as administrator, etc.) and it pretends to change it but then always sets it back to read-only

在Vista上编辑IIS7上的Web文件的工作方式是什么？
