[tw5] How to link to file using relative path added in an anchor tag?

I have a pdf on my local machine which is generated by converting an HTML file. I have one anchor tag in the pdf doc and I’m trying to have an anchor tag in the pdf and the path of the anchor tag to have a link to a subfolder present in the sibling folder of the pdf doc.
So, with that link, I want to open the subfolder in windows explorer.

Open D1

I want to have a relative path so that its a generic link, but with a relative path it’s not working, and its working only with an absolute path.
How to fix this issue?
