Loading a PDF from a CD

YO guys…!! how you all doing? i hope someone can help me with this… it may sound stupid but im totally lost in this:
well the problem is that im making a presentation in a CD its only like a menu 10 buttons thats it… the thing is that those buttons should load pdf files storeged in a folder in the same cd… im was trying with the following code but it open the files in a IE window…

this.onRelease = function(){ 
 getURL("info/1 - Frequently Asked Questions.pdf","_blank");

is there a way that pdf files get loaded directly in the adobe reader?
