i need a way to delete all security entries used to customize permissions of files and folders of an ntfs volume. consider when i convert a fat32 partition to ntfs and i've not customized or set or changed security/ownership of any file or folder. it's set to default. i don't know what's the default. i don't want to set, because it overrides the defaults. i want to reset permissions so that no file or folder has customized permission and use its parent permissions. at root, it should be the default also, and not been set.
