RFI:Emulating large filesystems.



Hi,

I want to write a emulator which can emulate a disk. Basically i want
to create large filesystems(~32TB) and large files(~2TB) but i do no
have such huge amount of space.
I want to know what it takes to develop such a emulator.
Can somebody please direct me in this regard.
