StorageFolder folder = Windows.ApplicationModel.Package.Current.InstalledLocation;

StorageFile file = await folder.GetFileAsync(path);

FileSavePicker savePicker = new FileSavePicker();

savePicker.SuggestedStartLocation = PickerLocationId.DocumentsLibrary;

savePicker.SuggestedSaveFile = file;

// Dropdown of file types the user can save the file as

savePicker.FileTypeChoices.Add("MP3", new List<string>() { ".mp3" });

// Default file name if the user does not type one in or select a file to replace

savePicker.SuggestedFileName = "New Document";
