When using NtCreateFile when creating a directory that already exists, it will correctly return 'STATUS_OBJECT_NAME_COLLISION'. However using this function to create a directory (and all its parents) a normal use would be to start with mkdir(‘/cygdrive/c’) which translates to ‘C:\’ for which it'll instead return ‘STATUS_ACCESS_DENIED’.
