@hrba It's a missunderstanding, all original files must be included. What @jakzal said is that if you don't translate a file, you don't have to duplicate it. (it's not easy to explain, I'll use an example)

- `/en/about.html.twig` translated in EN must be included
- `/pl/about.html.html` translated in PL must be included
- `/pl/about.html.twig` ducplicated from `/en/about.html.twig` and still translated in EN must **not** be includecd

Is my explanation okay?
