SqLite database persistence on mobile air application

Question

Hi, I'm Fabio from Italy. I'm developing a flex mobile application running on iPad, that application stores user settings in a local sqlite database on documentsDirectory. I've noticed that folder is destroyed and recreated each time the application is updated, and this is not good for user data . Is there any way to store that database in a folder that's NOT involved in the application uninstall/update procedure?
Thank to all!

You can't write anything to the applicationDirectory.
Use File.applicationStorageDirectory instead
Also you get path and do not wrtite to it anyting
var jpgEncoder:JPGEncoder = new JPGEncoder(90);
var byteArray:ByteArray = jpgEncoder.encode( bitmapData );
// set an filename
var filename:String = "cool-wallpaper.jpg";
// get current path
var file:File = File.applicationDirectory.resolvePath( filename );
// get the native path
var wr:File = new File( file.nativePath );
// create filestream
var stream:FileStream = new FileStream();
//  open/create the file, set the filemode to write; because we are going to save
stream.open( wr , FileMode.WRITE);
// write your byteArray into the file.
stream.writeBytes ( byteArray, 0, byteArray.length );
// close the file. That’s it.
stream.close();
Try to use:
// get current path
var file:File = File.applicationDocumentsDirectory.resolvePath( filename );
//  open/create the file, set the filemode to write; because we are going to save
stream.open( file , FileMode.WRITE);
