Actually,
The maximum file size is a function of the filesystem used for the disk
partition AND the OS.
For FAT/FAT32 partitions the maximum file size is 2^32 - for NT and
2000.
For NTFS partitions the maximum file size is 2^64, although my
research/searches showed that MS only implemented 2^41 support (but 2
terabytes should be enough for 99.999999999% of us) -- but that may have
changed.
In reality, the implementation of NT/2000 actually means that the true
maximum file size is significantly lower that the theortical limits --
something about the core memory allocation logic for paged and non-paged
memory.
For the record, the largest FB/IB database ever reported was some 980GB
in size.
