If you mean that you think this is the only FF7PC demo, you are mistaken. I have a non-3dfx demo from Eidos that came with Tomb Raider 3. I only got it for the FF7PC demo. Actually, there are two demos. One is the same stretch as your glide one, only it's in DirectX, the other is battle square, DX. Battle is 20megs, Corel is about 130, unrar'd. If you mean that yours is the only 3DFX demo, then.. well, you're probably right. If anyone wants the one that I have, to compare the directx and 3dfx of the identical thing, whatever, I'll be happy to share it, but I lack a host. Someone else will have to host it.
