Free .zipx extractor???

Mother fucker. Someone sent me a butt-ton of photos for work. The problem is, he sent them to me in .zipx format. As far as I can tell, there isn't a free app to extract zipx. My customer is too fucking cheap to get it for me but I don't know if my boss can get it for me to install on my customer's computer.

So I was going to just download a trial version to my personal computer, extract everything and git'r dun. Like everything else this weekend, that's easier said than done.

Does anyone know a free (even a 30 day trial) extractor that'll handle .zipx files?

I found this, but make no claims about its usefulness.

Never mind. Found a free trial version of WinZip.

Tell that moron to get 7zip. It's fucking 2010. Paying for file compression is being stuck on stupid.

Ah, but 7zip won't do .zipx files.

7-zip was my first thought as well because that's what I use, but I checked and was disappointed to find out it didn't handle zipx.

I'm pretty sure WinRar does everything, and it just nags you to pay, but never makes you.

Ah, never mind. Forgot this wasn't the Red Room.

Skin's never seen a .zipx archive.

Probably related to the stupidity of the .docx format that Office 2007 introduced
