Tip: Page > URI Links to File Shares
A quick tip for anyone who is trying to add a URI link to a file or folder share on their network and PC.
If you escape the link in the following way (source: stackoverflow.com/.../an-url-to-a-windows-shared-folder):
<a href="file://///server01\fshare\dir1\dir2\dir3">useful link </a>
You will get a valid working URI link (works in Internet Explorer only as far as I am aware). The link provided above also demonstrates how to enable the links to work with Firefox browser.
