How to create hyperlink to locally stored HTML files

[ghost]

I am unable to figure out how to link to locally stored .html files from the theme. I successfully created a new blog post under docs and on clicking on it I am able to view the related text. I also added a hyperlink to that same .md file (under docs folder) but the website is unable to render it. It shows 404 not found error. However, I have ensured that the .html file exists in the specified location and the path to the .html file is also correct. How do I fix this?
