Help please! Cabinet File???

Hello everyone!
I'ma newbie and having a problem on installing the gauges for AC520 panel! :-[
There was two zip files at the gauges folder, i've unzipped them to the gauges folder of FS2002 like the readme file guides me to do so.
I've took a flight with the plane but there were no instruments.
There was a screenshot at the how to install the Gauges file and there, the gauge zip files were at the cab format but i can't do that.
My question is how will i convert that zip file to cab format???
Thanks in advance! :)
