默认目录的权限是继承父目录的，你当然可以关闭它的继承和分配指定的权限。
下面例子创建了“PermissionNoInheritance”的文件夹，允许当前用户读取，同时管理员组获得其所有管理权限，并关闭它的继承。
# create folder $Path = ‘c:\PermissionNoInheritance‘ $null = New-Item -Path $Path -ItemType Directory -ErrorAction SilentlyContinue # get current permissions $acl = Get-Acl -Path $path # add a new permission for current user $permission = $env:username, ‘Read,Modify‘, ‘ContainerInherit, ObjectInherit‘, ‘None‘, ‘Allow‘ $rule = New-Object -TypeName System.Security.AccessControl.FileSystemAccessRule -ArgumentList $permission $acl.SetAccessRule($rule) # add a new permission for Administrators $permission = ‘Administrators‘, ‘FullControl‘, ‘ContainerInherit, ObjectInherit‘, ‘None‘, ‘Allow‘ $rule = New-Object -TypeName System.Security.AccessControl.FileSystemAccessRule -ArgumentList $permission $acl.SetAccessRule($rule) # disable inheritance $acl.SetAccessRuleProtection($true, $false) # set new permissions $acl | Set-Acl -Path $path
