自动解压文件【马上接帖】

[我辣椒哥]

Set Shell = Server.CreateObject("WScript.Shell")
rarcomm= "D:\email\page\mian\cmd.exe /c "&Mlpath&"rar.exe x -t -o+ -p- -e "
cmd=rarcomm&ywj&" "&ylj
'response.Write cmd
RetCode = Shell.Run(cmd,1, True)

上传123.rar到服务器名称修改成20111215.rar，执行到rar.exe x -t -o+ -p- -e将文件解压后得到的文件夹名称是123，如何解压20111215.rar得到的文件夹名称为20111215而不是123，如何修改呢？？？

rar.exe x -t -ad -o+ -p- -e

如果压缩包名称是20111215那么解压出的文件夹就是20111215
我是这样理解的你只是把123.rar改名为20111215 但是123.rar里面包含一个123的文件夹，所以你解压20111215出现的是123.rar里面的123文件夹。你只是把压缩包的文件名改了而里面的内容没改？如果是这样的话，压缩前就应该改名，或者解压后改名
或者
也许是我理解错了
