Filesystems can have 64bits internal on a 32bit arch system.
There is no relationship between the two.

To handle objects bigger than 4GB (2^32 Bytes), pointers must have more than 
But when you programme, you can use pointers of the size you want.

64bit CPU arch is usefull just to let the processor directly address memory 
higher than 4GB.
