Question : Problem: Unzipping only certain files in a ZIP folder

I thought this would be relatively simple, but it's become a real challenge.

I have several hundred relatively small files in a directory. They're all zip files. Inside each one is a file with a specific extension, .vpt. I want to extract JUST the .vpt files and place them all into one directory.

But I'd like to find a program or utility that can do this for me, since it will take a long time to unzip each one into its own folder and then copy the .vpt files one at a time into a separate folder.

II've looked for a program to do this and thought I found the solution 3 or 4 times, but none will do this specific task.

Know of a program or simple way to do this?

Shouldn't be a problem. Google "pkzip command line," it will get you the tool. I know PKware sells one but you can probably find one for free. The command line tool will allow you do to this.
