Where do you notice a shortcoming of PTB?\n\nThe `telegram.File.download_to_drive` method is an async coroutine, but it performs synchronous file I/O (`.write_bytes`, `shutil.copyfile`).\n\nThese blocking calls can stall the asyncio event loop, especially with large files or heavy I/O load. This undermines the non-blocking promise of an async method and can hurt a bot's responsiveness.\n\n### Describe the solution you'd like\n\nThe method should be made fully asynchronous by replacing all synchronous file operations with non-blocking alternatives from the aiofiles library.\n\nThis change would make the entire file download process truly non-blocking.\nI am happy to prepare and submit a Pull Request to implement this feature.\n\n### Describe alternatives you've considered\n\n_No response_\n\n### Additional context\n\n_No response_","author":{"url":"https://github.com/aviadlevy","@type":"Person","name":"aviadlevy"},"datePublished":"2025-10-09T08:17:58.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":8},"url":"https://github.com/4993/python-telegram-bot/issues/4993"}
