How to open local file from browser?
How can I create a link to a local file on a locally-run web page?
html link to local file and open in local application
<a href='file:///Z:\\Fixed Line\\Design & Build\\2. Clients\\Openreach\\3. MDU Designs\\Coventry\\OR66 - Priory Court, Coventry\\
this code works when I want to open the local file in the browser.
I tried to put another code regarding to https://en.wikipedia.org/wiki/File_URI_scheme
<a href='file://///Z:\\Fixed Line\\Design & Build\\2. Clients\\Openreach\\3. MDU Designs\\Coventry\\OR66 - Priory Court, Coventry\\
But it still open in the browser.
I want to have it opened in Windows (or another local application) instead the Chrome (or another browser).
