Recursively set permissions on folders using Powershell?
Use SetAccessRuleProtection() to disable inheritance and remove inherited ACEs:
$acl.SetAccessRuleProtection($true, $false)Use RemoveAccessRule() to remove existing (non-inherited) ACEs:
$acl.Access | ForEach-Object { $acl.RemoveAccessRule($_) | Out-Null }Use AddAccessRule() to add new ACEs:
$ace = New-Object Security.AccessControl.FileSystemAccessRule "user", ...$acl.AddAccessRule($ace)...Do this only for the topmost folder. Leave inheritance enabled everywhere below, so your changes are propagated automatically.
