文件、目录，文本文件等多种操作类
一个使用fso的class，前面的文章也有提到。这里有比较多的一些实例。 <% Dim MyFileFolder Set MyFileFolder = New FileFolderCls ''Response.Write MyFileFolder.MoveAFile("f:\123\4561.exe","f:\123\4562.txt") ''Response.Write MyFileFolder.MoveAFolder("f:\456","f:\ditg\456") ''Response.Write MyFileFolder.ShowFileSystemType("i:\") ''Response.Write MyFileFolder.CopyAFile("f:\123\4562.txt","f:\123\4563.txt") ''!!!!
