vs1    1    Security Style: NTFS and     Access is allowed because
                 NT ACL    explicit ACE grants requested
                       access. Access is denied. The
                       requested permissions are not
                       granted by the ACE while
                       checking parent's modebits
                       during delete. Access is not
                       granted for: "Execute",
                      "Write"
