I think many programmers have used file splitting technology at the application level for decades. I know I wrote one for a backup utility (Drive Image) back in the 90s that would split the output files into smaller pieces for transfer to removable media (floppies, Zip drives, CDs, DVDs, etc.).

It sounds like BigFat is an extension that takes away the need to do this at the application level. The code does all the splitting and merging for you so you can write a program that acts like the file is on a file system that supports files > 4GB.
