I'll need to backup the game known as Witcher 2, which is obviously 16GBs of data of... Triss? Anyways, I am going to be really specific about how I back it up. I'm not interested in buying an extra hard drive for backup or stuffing the game on a USB flash drive or MicroSD card. I'm in love with good DVDs and I have tons of them at this point.

However, I'll need a way to backup the Witcher 2's data so that I install the first disc, then be prompted to insert the second disc to continue extraction, and so on. I'd love for my backup installer to be this clean. The goal here is to make the extraction of the Witcher 2 backup as lovely as any multi-disc game out there.

Anyone knows a secret or two about that?

I will see to it that your solution works when I download TW2. In the meantime, thanks for the answer!

Hmmm if the bin files are larger than 4Gigs, you can use 7zip, set it to 'store' and tell it to split the archive to files of a specific size (DVD is preset as a size), then burn those files. But if the installer files ARE less than 4Gigs per, then burning them as is IS the better option (no intermediate pack/unpack steps).

It works just as you explained, though I'll need to try them all out before I run into an error late in the process. The installer will ask for the parts, and then you lead them to where each part is before it continues the setup.

You are the solution.
