I have to save files from folder on skdrive to my isolated storage (if files in isolated storage exist then override them).

This is my code:

Code:
private void RestoreData(LiveConnectClient liveClient, string storedFolderId)
    {
        liveClient.DownloadCompleted += liveClient_DownloadCompleted;
        liveClient.DownloadAsync(storedFolderId + "/content");
    }

    private void liveClient_DownloadCompleted(object sender, LiveDownloadCompletedEventArgs e)
    {
        Stream stream = e.Result;

        // HOW TO SAVE FILES ON IN THIS METHOD?
    }
How can I save files in method liveClient_DownloadCompleted?
