any modern  *NIX  OS can do this :)
A 4 GB file is not a weird thing: I save blu-ray images on my HDD which are
+/- 50 GB in filesize :)

you can write of course your own simple program to do this. It's not because
an existing program doesn't support it, it's impossible. And of course in
the near future programs will be able to work with files as big as 1 TB and
even bigger. And that was exactly the thing I was talking about :)
