-#### Видишь проект в папке?

-Okay, the user is asking if I can see the project in the folder. But since they mentioned they're not sharing any files yet, I need to respond appropriately. Let me check the previous messages again.
-
-Earlier, the user said they switched to a new codebase and don't want the assistant to consider previous files. Then they stated they aren't sharing any files for editing. Now, their latest message is in Russian: "Видишь проект в папке?" which translates to "Can you see the project in the folder?"
-
-Since they haven't provided any files or project structure, I can't see any files. My response should inform them that I can't access or see any files unless they share them. Also, I should prompt them to provide the necessary files or details for assistance. Need to make sure I follow the guidelines of not making assumptions and only working with provided information. Let me phrase it clearly in Russian as per their request.

-Нет, я не вижу проекта в папке. Пожалуйста, поделитесь файлами или укажите, какие изменения вы хотите внести, и я помогу вам с ними.
