bitmapImage.SetSource(fileStream);
img.Source = bitmapImage;
this.DataContext = file;
}
}

Use StorageFile.CopyAsync , that is, file.CopyAsync. The first argument is the destination StorageFolder, eg Windows.Storage.ApplicationData.Current.LocalFolder if you wanted to copy to appdata; otherwise you'd need to create a folder or get one from a picker separately.
You might, for example, have the user choose a default folder with the file picker (configured for folders). Just be sure to save that StorageFolder in the [Windows.Storage.AccessCache][2]
to preserve programmatic access for future use.
