Best Way to keep Settings for a WinRT App?

I'm working on a WinRT app that's actually also a game. I need to keep different information such as audio settings or player statistics somewhere in sort of a file or somehow. If it's a file, just write settings in or... ? I have an idea but I think is way too rudimentary... What is the best approach to obtain this?

Any help or suggestions are greatly appreciated!

Here are some ways to save Data in a WinRT app, the method with Settings in the name is probably what you are looking for!- just added the other ones as well,- you also can serialize data if you want to. This is working code- but don't forget to add error handling etc. It's a simple demo code :)

As for settings, you can save simple settings as key and values, and for more complex settings you can use a container. I've provided both examples here =)

 public class StorageExamples
{
    public async Task<string> ReadTextFileAsync(string path)
    {
        var folder = ApplicationData.Current.LocalFolder;
        var file = await folder.GetFileAsync(path);
        return await FileIO.ReadTextAsync(file);
    }

    public async void WriteTotextFileAsync(string fileName, string contents)
    {
        var folder = ApplicationData.Current.LocalFolder;
        var file = await folder.CreateFileAsync(fileName, CreationCollisionOption.ReplaceExisting);
        await FileIO.WriteTextAsync(file, contents);
    }

    public void SaveSettings(string key, string contents)
    {
        ApplicationData.Current.LocalSettings.Values[key] = contents;
    }

    public string LoadSettings(string key)
    {
        var settings = ApplicationData.Current.LocalSettings;
        return settings.Values[key].ToString();
    }
    public void SaveSettingsInContainer(string user, string key, string contents)
    {
        var localSetting = ApplicationData.Current.LocalSettings;

        localSetting.CreateContainer(user, ApplicationDataCreateDisposition.Always);

        if (localSetting.Containers.ContainsKey(user))
        {
            localSetting.Containers[user].Values[key] = contents;
        }
    }
}
