What kind of feature are you missing? Where do you notice a shortcoming of PTB?
The telegram.File.download_to_drive method is an async coroutine, but it performs synchronous file I/O (.write_bytes, shutil.copyfile).
These 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.
Describe the solution you'd like
The method should be made fully asynchronous by replacing all synchronous file operations with non-blocking alternatives from the aiofiles library.
This change would make the entire file download process truly non-blocking.
I am happy to prepare and submit a Pull Request to implement this feature.
