Anyone know what archive format NVIDIA uses for sdk exe? I want to extract the SDK sources without i

Hi folks,
Does anyone know what archive format NVIDIA is using for the SDK exe?
I want to extract just the sources from the 2.0 SDK, without “installing” and messing up my 2.21 installation.
I tried 7zip and winzip, no luck.
Any other tool recommendation?

TY!

After more googling and a trying a few others, I finally did the trick with
Universal Extractor, [url=“Universal Extractor | LegRoom.net”]http://legroom.net/software/uniextract[/url]

The file is an installshield archive, with internal installshield cabinets.
So I extracted the sdk.ext, then extracted the data1.cab, and there’s the “projects” sources.

There may be an installshield option to extract without installing, but I don’t know what it is for this archive.
