Deleting a File

To delete a saved 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 deleted.

  4. Call File.Exists to confirm that the file is present.

  5. Call File.Delete with the file name of the file to delete.

  6. Call the StorageContainer method to commit the changes to the device.

private static void DoDelete(StorageDevice device)
{
    // Open a storage container.
    StorageContainer container =
        device.OpenContainer("StorageDemo");

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

    // Delete the new file.
    if (File.Exists(filename))
        File.Delete(filename);

    // Dispose the container, to commit the change.
    container.Dispose();
}
