     First at all: please, include into quote only relevent part, not all
original letter, including service parts. Second: _FAT32_ is _not_ limited
to 40 Gb. This limitation may be applied to some rude operating system, but
FAT32 _file system_ itself is limited by 2 Tb.

     Easy arithmetics: 32-bit FAT entries mean 2^32 clusters (4G) clusters.
With 32 kb (2^15) for each cluster, we may have 2^47 bytes (read: 128 Tb).
But remember, that sector counters in file system descriptors limited to 32
bits and this restricts FAT32 by 512 bytes*2^32=2^41 bytes (2 Tb).
