Wait, in 2021, there were rumors about Yandex working on some projects related to artificial intelligence or cloud services. Maybe Nippyfile is related to that. Alternatively, it could be a file-sharing feature within their ecosystem. Let me think. Yandex has a browser and cloud storage. If they developed a new file management or sharing tool, it might be referred to in internal documents as Nippyfile. Maybe it's a way to handle files more efficiently, integrating with their AI models.
