Often, you may need to create a new folder and also set NTFS permissions for the folder.
Here is a simple example that creates a new folder and illustrates how you can add new permissions to the existing permissions:
$Path = 'c:\protectedFolder' # create new folder $null = New-Item -Path $Path -ItemType Directory # get permissions $acl = Get-Acl -Path $path # add a new permission $permission = 'Everyone', 'FullControl', 'ContainerInherit, ObjectInherit', 'None', 'Allow' $rule = New-Object -TypeName System.Security.AccessControl.FileSystemAccessRule -ArgumentList $permission $acl.SetAccessRule($rule) # add another new permission # WARNING: Replace username "Tobias" with the user name or group that you want to grant permissions $permission = 'Tobias', 'FullControl', 'ContainerInherit, ObjectInherit', 'None', 'Allow' $rule = New-Object -TypeName System.Security.AccessControl.FileSystemAccessRule -ArgumentList $permission $acl.SetAccessRule($rule) # set new permissions $acl | Set-Acl -Path $path
