How to open a new folder then select a file?

Question

when we use a mp3 player(desktop app).we can view the song in a new folder after we right click on it and choose view.how to do it on air?
all i can do is just like this:
var file:File = new File();
                                        file.nativePath=songArray[rolloverItemIndex].url
                                        file=file.parent
                                        file.canonicalize()
                                        file.openWithDefaultApplication();
just open new folder but can't auto selecte the file that i want.

Check this code it will work
try
File f=new File("NewDocument1.doc");
FileOutputStream fos=new FileOutputStream(f);
FileInputStream fis = new FileInputStream(f);
FileChannel fc = fis.getChannel();
byte[] data = new byte[(int)(fc.size())];
IWDCachedWebResource cachedWebResource=WDWebResource.getWebResource(data,WDWebResourceType.DOC);
cachedWebResource.setResourceName("NewDocument1.doc");
String url=cachedWebResource.getURL();
IWDWindow window=wdComponentAPI.getWindowManager().createExternalWindow(url,"cmps",true);
window.open();
catch(Exception ioe)
wdComponentAPI.getMessageManager().reportSuccess(ioe.getMessage());
wdComponentAPI.getMessageManager().reportException("Exception in Method cmps :::"+ioe.getMessage(),false);
