Extract spawned page to folder

Is it possible to Spawn a template page  and then extract it to another folder?

This is what i have so far but I get a range error…

    var t = this.getTemplate("MyTemplate");   

    //var T = t[0];

    var XO = t.spawn(this.numPages, true, true);

    for (var i=0; i<0; i++) t.spawn(this.numPages, true, true, XO);

this.pageNum++;

    /* Extract pages to folder */

    // Regular expression used to acquire the base name of file

    var re = /\.pdf$/i;

    // filename is the base name of the file Acrobat is working on

    var filename = this.documentFileName.replace(re,"");

    try {for (var j = 0; j < this.numPages; j++)

            this.extractPages({

                nStart: j,

                cPath: "/MyComputer/Desktop/MyFolder/"+filename+"_" + j +".pdf"

            });        

    } catch (e) { console.println("Aborted: " + e) }
