blackberry-10 - BlackBerry 10 Native SDK - Writing Text Files

Question

I am battling to write some data to a simple text file
Here is my code:

QFile file(app->applicationDirPath() + "/data/testfile.txt");

if (file.open(QIODevice::WriteOnly)) {
    QTextStream stream(&file);
    stream << "DATA HERE \n";
}

The app compiles and runs fine.

Just I cant find the file, or more likely: it is not being created

Where am I going wrong? :)

Thanks

Extra Info:
Run: on my device (BlackBerry Z10)
IDE: QNX IDE (Native SDK) / (Cascades)
Example code is located in: TestApp::TestApp(bb::cascades::Application *app) : QObject(app)

好的，我自己偶然发现了答案：

QFile file(QDir::currentPath() + "/shared/documents/yourfile.txt");

if (file.open(QIODevice::WriteOnly)) {
    QTextStream stream(&file);
    stream << "DATA HERE \n";
}

原来每个应用程序都可以访问自己的工作目录。所以正在创建文件，我只是在设备上看不到它：

制作路径：“/shared/documents/”将文件放在我可以在文件管理器中看到的地方
