[CA] c120 software update

I downloaded the most recent software for my c120 classic. One file is C_App_Prod516.pkg. The video shows opening this and then copying individual files to the root of the CF card. I can not open this. For "type" this says file not folder so I am not sure additional file exist. I have tried this in my C120 but I do not get any update utility screens. Do I need to do something different on my CF card or when copying these files?

Thank you for the help.
