1. Is this request related to a challenge you're experiencing? Tell me about your story.

When I am operating the Dify workflow, I am facing two problems:

1. I want to save my output in the form of a file, but I don't know how to do it. Should I use Python code or a corresponding plugin? However, I haven't found a plugin with this function.
2. I have another problem. When my knowledge base returns a local link to a file, I want to read this document. I think this involves reading local documents.

2. Additional context or comments
