如何使用VBScript删除temp文件夹中以特定名称开头的所有文件

Question

我正在尝试使用以下VB脚本从Windows Temp文件夹中删除所有以字符串“ MyApp”开头的日志文件。

Dim objFSO
Set objFSO = CreateObject("Scripting.FileSystemObject")

if objFSO.FolderExists("C:\Documents and Settings\guest\MyApp") Then
          set folder = objFSO.getFolder("C:\Documents and Settings\guest\MyApp") 

if folder.files.Count <> 0 then 
    objFSO.DeleteFile "C:\Documents and Settings\guest\MyApp\*.*", True
end if 
          objFSO.DeleteFolder "C:\Documents and Settings\guest\MyApp", True
end if

<!--  The below code is not deleting the files which starts with the name "Mpp.023648011.log"   -->

if(objFSO.FileExists("C:\Documents and Settings\guest\Local Settings\Temp\MyApp.*")) Then
    objFSO.DeleteFile "C:\Documents and Settings\guest\Local Settings\Temp\MyApp.*", True
end if

似乎以下检查失败：

if（objFSO.FileExists（“ C：\ Documents and Settings \ guest \ Local Settings \ Temp \ MyApp。*”））

提前致谢。

我找到了一种抑制错误消息并执行DeleteFile的方法。它为我工作。

     On error resume next

     objFSO.DeleteFile "C:\Documents and Settings\guest\Local Settings\Temp\MyApp.*", True

我认为VBScript不支持使用通配符的FileExists。更好的选择是仅抑制删除操作中的错误并运行DeleteFile命令。

 On error resume next

 objFSO.DeleteFile "C:\Documents and Settings\guest\Local Settings\Temp\MyApp.*", True
