So good of you !
I remember thinking about how to tackle such a situation in linux. But never got around to trying it. Also from theoretical thinking, I expected there to be more than just the file extensions to determine the order. I thought there would be some special character or codes at the end and start to delimit the main data segments and so I will have to cut those and assemble the rest in order to get to the whole. But now that I think of it, this indeed seems the simplest logical solution.

Thanks for this.

re. now go and find out how to do this segmentation of a big file in linux with some simple tool that does just the opposite of cat at pre specified data limits.
