7.7 Microsoft Windows NT

    
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. (guy@netapp.com (Guy Harris), 95/10/6)
