Can we extract the contents of a *.vpk file?

I have a copy of it (It's attatched.), but it only works on one of the VPL files... the other remains tantalizingly out of reach with this tool.

What I was looking for, but was unable to find, was the objects in-game in some kind of 3D format, and/or the textures that go on said objects.
