To simplify referencing the same files, a user can leverage two distinct methods. First, the Notebook feature within the main Copilot interface allows for drafting, editing, and saving complex prompts that can reference specific files, making it easy to reuse the context without re-uploading. Second, for a more robust and permanent solution, the user can use Microsoft Copilot Studio to create a custom agent (a topic-specific copilot). By uploading the five files as a knowledge source to this agent, they become a persistent part of its grounding data, accessible in any conversation with that agent.

A. Saving a prompt in the Prompt Gallery saves the prompt text but does not retain any file attachments.

C. Fine-tuning a large language model is a highly complex, developer-centric task for altering core model behavior, not for simple file referencing.

E. Zipping files streamlines the upload process into one action but still requires the user to manually upload the file in each new chat.

2. Microsoft Copilot Documentation. (2024). Using the Notebook interface. "Notebook is a new interface... that lets you iterate on your prompts. It's a great place to refine your prompts and ensure you get the best possible response." This interface is used to maintain context, including file references, for reuse.
