Cant burn Raspberry Pi 2 kali-1.1.0-rpi2.img.xz to SD using Windows 8.1

Hello, First some basic information:

I've been using the new Raspberry 2 1G for four months now. I am alright
with Linux, but other than the NOOBS install for raspberry pi, I haven't installed
anything from an SD Card. Plus the NOOBS d/l was a regular *.img file.

I have followed all the directions to download kali-1.1.0-rpi2.img.xz and have
checked the SHA Hashes and everything is fine, BUT

I just cant figure how to burn the image on the SD card with the img.xz on the end!
Nothing I have found addresses a .xz file and I have downloaded all the programs
in the instructions I could find.

Ive searched and I guess I am the only moron with this issue because I have
been looking now for days and nothing... Could someone please help.

Thank you!

A . xz is an archive. Extract it first and then image it on your SD card.

7zip on Windows can extract it (cause you said you're using Windows)

Thanks so very much, that never crossed my mind.

Just as you said, once extracted everything was fine and I can take it from here!

I really appreciate the assistance!
