I seem to recall that NT supports 64-bit file systems for its own native file systems? Anybody know for sure (SHMO)? (rdv, 94/8/24) From Inside the Windows NT(TM) File System, by Helen Custer: "NTFS allocates clusters and uses 64 bits to number them, which results in a possible 2^64 clusters, each up to 4KB. Each file can be of virtually infinite size, that is, 2^64 bytes long." "Clusters" can be between 512 and 4K bytes. The Win32 API supports 64-bit file sizes, albeit in a cheesy fashion reminiscent of V6 UNIX - no 64-bit integral types used, just pairs of 32-bit integral types.
