神马品牌网韩国新生活化妆品加盟:如何用asp创建 删除 文件夹？

用FSO组件来实现
filesystemobject组件 又名 FSO
下面是它的一些实例：
fso的一些用法
fso的一些特殊功能
下面列举一下这些不常用但是却非常酷的功能：
很少被了解的FSO功能
GetSpecialFolder Method 返回特定的Windows文件夹的路径: Windows安装目录；Windows系统目录；Windows临时目录 FSO.GetSpecialFolder([0, 1, or 2])
GetTempName Method 返回一个随机产生的文件或者目录名字，用于需要存储临时数据时
GetAbsolutePathName Method 返回文件夹的绝对路径(类似于Server.MapPath)。
比如，FSO.GetAbsolutePathName("region") 将返回类似于下面的结果："c:mydocsmyfolder egion"
GetExtensionName Method 返回路径中最后部分的扩展名
(比如：FSO.GetExtensionName("c:docs est.txt") 将返回txt)
GetBaseName and GetParentFolder Methods 返回路径中最后部分的父文件夹
(比如：FSO.GetParentFolder ("c:docsmydocs") 将返回\'docs\')
Drives Property 返回所有本地可用驱动器的集合，用于建立资源浏览器样的用户接口。
使用上面的功能时，最好建立好出错处理的代码。因为如果需要的参数不存在，将会产生麻烦的信息。
使用FSO按文件大小浏览文件目录并进行删除操作
