Link to document in comment field

Hello,
if I enter a URL (www.google.com) in a comment field, it is possible to open the page by just clicking on the link. What I want to do is put a link to a local file in a comment field, so that clicking on the link opens the document (for example: c\files\example.pdf). Is that at all possible ? What would the link have to look like?
Thanks for any useful advice!

Hello,

I don’t think web browsers will allow you to open links to local file address. you can try to prepend file:// to specify the local URL.
