The question i pose to you is why do you wish to extract them all?

Probably because I'm a total newbie, and out of curiosity just want to see what's in the Drive Packs.

I had ideas of learning how to manually install any missing drivers from the extracted driver packs, onto my slipstreamed installation image, but that is not necessary according to the beginners tutorial, which I'm just about to get my head around?

Maybe I'm taking a sledgehammer to crack a nut by that approach?
Is this a better alternative. Please see my reply #22:

All main NT5 and NT6 (x86 and x64?)
OR
all main and 3rd party DriverPack for both NT5 and NT6... (x86 and x64?)

which versions will you use?

In any event it's a lot... and it is subjective...
IE 999 out of 1000 people would never need or include LAN RIS
Perhaps you don't need the printer pack, ETC....

it's easy to find out... each download page lists the extracted and compressed sizes. Simply add up the extracted sizes of the ones you want.

extracted that pack is 386 MB... or 405 million bytes (listed as 'original size')

We can't answer that question for you... At least not accurately / precisely. There are simply too many variables. IE what is your cluster size? This will directly effect the actual space required on the media.
The info is available to you, and without you having to actually extract them

I have run out of disk space trying to extract all the archives.

I also need to know what size USB flash drive to get, to put the extracted DP archives on.

TIA

Edit: I have removed the extracted DP's, and there was 11GB of free space before I started to extract all the DP's, but that was not enough as I previously checked the free disk space before removing the extracted files, and it was 0%. The error message was:
