Getting a parent's parent for a folder using power shell

suren424 

the script seems to be working,

I try it on my side and the result was correct, good job.

$Permission.SetAccessRuleProtection($False,$true)
Set-Acl -Path $allFolders.FullName -AclObject $Permission

In the first line and as the $Permission is holding the folder ACL information, there is one of the methods called SetAccessRuleProtection, you can find all other methods and properties by using $Permission | Get-Member.

More info here

The SetAccessRuleProtection accepts 2 input IsProtected and PreservedInheritance 

SetAccessRuleProtection (bool isProtected, bool preserveInheritance);

IsProtected: Type is Bool ($True/$false) , $False= Enable Inheritance

PreservedInheritance : This parameter is actually ignored as the IsProtected is set to false

Thanks
