Does XP's built-in WinZip have a command line interface?
 

I have a lot of .zip files that I would like to extract from but I'd hate to extract them out by hand. I could easily write a script to do such a thing if only my zipping program had a comand line interface. Unfortunately, I've been using the built-in zipping facilities of WindowsXP, under the assumption that it will "do it all" for me and it has no obvious command line interface.

So, is this a pipe dream or is there actually a command line interface for this feature?
Thank you...

No.

Try the command line version of PowerArchiver: http://www.powerarchiver.com/download/.
