可以列出目录中的文件,但要列出所有目录中的文件

<% ListFolderContents(Server.MapPath("/path/to/main/folder")) %>
<% sub ListFolderContents(path)

     dim fs, folder, file, item, url

     set fs = CreateObject("Scripting.FileSystemObject")
     set folder = fs.GetFolder(path)

    'Display the target folder and info.

     Response.Write("<h2>"& folder.Name &"</h2>")

     'Display a list of sub folders.

     for each item in folder.SubFolders
                ListFolderContents(item.Path)
     next

     'Display a list of files.
Response.Write("<ul>")
    for each item in folder.Files
       url = MapURL(item.path)
        Response.Write("<li><a href=""" & url & """>" & item.Name & "</a></li>")
    next
        Response.Write("</ul>")
   end sub


   function MapURL(path)

     dim rootPath, url

     'Convert a physical file path to a URL for hypertext links.

     rootPath = Server.MapPath("/")
     url = Right(path, Len(path) - Len(rootPath))
     MapURL = Replace(url, "\", "/")

end function %>
