一个简单的管理Web站点文件的页面程序（修改版）

news 来源：原创 2024/5/5 14:36:24

蛋疼之余，写了一个小程序，用于在页面中管理当前 Web 站点下的所有文件。可以对所有文件和文件夹执行重命名、删除等功能，也可以创建目录，上传文件，下载文件等。

不废话，先看效果：

贴代码：

  5 管理Web站点下文件的页面程序。
  6 提供上传、重命名、删除、创建文件夹、下载等功能。
  7 -------------------------------------------------
  8 于 2012-07-06 16:35 修改。
  9 修改“当前目录”保存方式，取消使用静态变量保存，使用 Session 对象记录当前目录。
 10 添加“当前目录”页面显示，显示当前操作所在目录（根目录名为“Root\”）。
