I can see the problem and get your point as I was in a similar situation . I don ' t know your specific scenario so I can only guess and make assumptions . I ' m sure AccessEnum is able to show only permissions that differ from a given parent . You can export the results and parse it via PowerShell to determine odd entries and proceed further . The same goes for the NTFSSecurity module . I assume you have a concept or baseline how permissions for a certain directory should look like . You need to because otherwise there is no chance to identify ' stray ' permissions . <| sep |> Don ' t drink too much water or you drown . <| sep |> Games tend to ' fill the disc ' and on PC they don ' t really care about space . But with cartridges larger capacities cost more to produce so developers are going to take a 40 GB game and squeeze it into 32 GB to avoid paying for 64 GB carts . This already happens to an extent on XB 1 PS 4 , but depending on how much more it costs to up cartridge capacity it could be a significant issue .
