I have just looked this up.  WinNT has a max partition size of 2TB
(2,199,023,255,552 bytes), and with the NTFS file system, using a 64-bit file
indexing, allowing file sizes of an amazing 16EB (exabytes)!
(18,446,744,073,709,551,616 bytes), even though NT itself couldn't handle nearly
such a big file, and of course no disk could come close to holding it either.
