C# Windows Phone 8.1 create file container

Question

I want to add multiple small StorageFiles (5-60 KB each) into one big container (ca. 1-3 MB with all files), that I can afterwards upload to OneDrive in Windows Phone 8.1.

What is a good and clean way to do that? Compression and/or Encryption is optional.

Answer 1

What about LocalSettings? You may try to store your files there.

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

    public string Load(string key)
    {
        return ApplicationData.Current.LocalSettings.Values[key] as string;
    }
