transfer of 9GB File piece by piece

[jojo11]

I need to break up a file into smaller parts (Current file is 9GB). Is there a way to move part of the file into a smaller new file and know where we left off to begin another transfer, and another, and another?

Thanks

Yep, you can open the file, read out n bytes of data, and save it to a new file. (and repeat until the end)

But if you are going to do this I'd consider making a header for each file section, such as the first n chars = file name, the next 2 bytes = parts (ie if you split it into 4 parts, I'd do 1 of 4, I'd also record the file size, adn maybe a checksum.)

That way you can reconstruct it.

I assume that you are going to write an ap to break down / rebuild this file, or do you want to extract say days 1 - n from the file and save as week 1, the next as week 2 etc ?
