.xfs is an archiving extention for Linux/SGI Irix. It's like a .zip file. Well..more like a .cab file actually. They're really not meant to be opened individually.
What's the file do for you. I probably have a utility that can open it if you're willing to spend like 3 hours installing a Linux dual boot on your machine :0 Or you could email it to me and I could open it for you.

To make a long story short, I don't take any responsibility for anything I post here. It's not news, it's not truth, it's not serious. It's parody. It's satire. It's bitter. It's angsty. Your mother's a *****. You like to jack off dogs. That's right, you heard me. You like to grab that dog by the bone and rub it like a ski pole. Your dad? Gay. Your priest? Straight. **** off and let me post. It's not true, it's all in good fun. Now go away.
