If it’s just a media file it should not be able to access anything except for extremely unlikely scenario. If it’s an application like a game it’s different and the solution depends on your OS.
Also tuta and proton work with tor:
- https://tuta.com/blog/tutanota-and-tor
- For proton you need to access it through its onion service: https://proton.me/tor
Is this with the tor browser? Are you using the onion service for Proton?
