    var zip = app.CreateZipUtil();
    zip.Open( file );
    var list = zip.List("").split(",");
    app.Alert(list.join(",\n"));
    zip.Close();
}

{
    var name = app.GetAppName();

    var file = "/sdcard/" + name + ".zip";
    app.ShowProgress();

    var zip = app.CreateZipUtil();
    zip.Create( file );
    AddFolder( zip, name, fldr );
    zip.Close();

    app.HideProgress();
    app.ShowPopup( "saved to " + file );
}

function AddFolder( zip, name, fldr )
{
    var list = app.ListFolder( fldr,"");
    for( var i = 0; i < list.length; i++ )
    {
        var title = list[i];
        if( !app.IsFolder( fldr + "/" + title ) )
            zip.AddFile( name + "/" + title, fldr + "/" + title );
