Opening a File

To open a save game file in title storage

  1. Call the Guide.BeginShowStorageDeviceSelector method to get a device index indicating which device the user prefers.

  2. Open a StorageContainer on the device, and then pass the name of your title.

  3. Call Path.Combine to merge the container path with the name of the file to be opened.

  4. Call File.Open with the file name of the file to open.

    File.Open returns a FileStream object that you can use to add data to the file.

  5. Call Close to close the file after you have read it.

  6. Dispose the StorageContainer after closing the file.

private static void DoOpen(StorageDevice device)
    // Open a storage container.
    StorageContainer container =

    // Add the container path to our file name.
    string filename = Path.Combine(container.Path, "demobinary.sav");

    FileStream file = File.Open(filename, FileMode.Open);

    // Dispose the container.
