Based on the available information, a Knowledge Base in Vapi is actually
a collection of custom files that contain information on specific topics. When you create a Knowledge Base, you're essentially uploading files (in Markdown, PDF, text, or Word format) and configuring them to be used by your assistant. Since a Knowledge Base is already a way of organizing and using files, it's unclear if there's a separate "files" feature that can be used simultaneously with it.
