Using JSX to create a folder Help [CS3].

Question

I'm trying to automate the zoomify export feature in photoshop CS3. It works fine until I try and save the file to a directory that does not exist. Instead of creating the directory, it throws an error and quits the script. So what I want to do is create a directory before I run the code to make the zoomify but I can't find a way to do so in google. Any help would be nice! Here is the code I was using.
var id12 = charIDToTypeID( "Expr" );
    var desc5 = new ActionDescriptor();
    var id13 = charIDToTypeID( "Usng" );
        var desc6 = new ActionDescriptor();
        var id14 = stringIDToTypeID( "template" );
        desc6.putPath( id14, new File( "C:\\Program Files\\Adobe\\Adobe Photoshop CS3\\Presets\\Zoomify\\Zoomify Viewer (Black Background).zvt" ) );
        var id15 = charIDToTypeID( "Otpt" );
        desc6.putPath( id15, new File( "P:\\upLoad\\item_zoom\\"+name1+"-"+name2 ) ); // This is where the error is hitting, where name1+"-"+name2 needs to be created.
        var id16 = stringIDToTypeID( "baseName" );
        desc6.putString( id16, imageZoom );
        var id17 = charIDToTypeID( "EQlt" );
        desc6.putInteger( id17, 8 );
        var id18 = charIDToTypeID( "Optm" );
        desc6.putBoolean( id18, true );
        var id19 = stringIDToTypeID( "browserWidth" );
        desc6.putInteger( id19, 540 );
        var id20 = stringIDToTypeID( "browserHeight" );
        desc6.putInteger( id20, 490 );
        var id21 = charIDToTypeID( "Prvw" );
        desc6.putBoolean( id21, true );
    var id22 = stringIDToTypeID( "Zoomify" );
    desc5.putObject( id13, id22, desc6 );
executeAction( id12, desc5, DialogModes.NO );

You can create the folder like this
var myFolder = new Folder('/p/upload/item_zoom');
if(!myFolder.exists) myFolder.create();
You just have to make sure that the parent folder exists as well, in this case '/p/upload'. If not you need to create that folder first then the subfolder.
You might also run into privilage issues with some OS.
