這篇文章主要介紹“vbs怎么通過WMI修改文件文件夾的NTFS權(quán)限”，在日常操作中，相信很多人在vbs怎么通過WMI修改文件文件夾的NTFS權(quán)限問題上存在疑惑，小編查閱了各式資料，整理出簡單好用的操作方法，希望對大家解答”vbs怎么通過WMI修改文件文件夾的NTFS權(quán)限”的疑惑有所幫助！接下來，請跟著小編一起來學(xué)習(xí)吧！

使用WMI修改文件文件夾的NTFS權(quán)限, 代碼：

復(fù)制代碼 代碼如下:

strUser = "guests"
strPath = "D:\\abc.txt"
RetVal = AddPermission(strUser,strPath,"R",True)

'-------------------------------------------------------------------------

'用于給文件和文件夾添加一條權(quán)限設(shè)置.返回值: 0-成功,1-賬戶不存在,2-路徑不存在
'strUser表示用戶名或組名
'strPath表示文件夾路徑或文件路徑
'strAccess表示允許權(quán)限設(shè)置的字符串,字符串中帶有相應(yīng)字母表示允許相應(yīng)權(quán)限: R-讀,C-讀寫,F-完全控制
'blInherit表示是否繼承父目錄權(quán)限.True為繼承,False為不繼承
