<!-- To create an HTML link to a UNC path, use the following format for the href attribute of the anchor (a) tag. file://///path/to/unc/share You must have *five slashes* at the beginning! The first three slashes are a part of the protocol "file:///" (yes, indeed it is supposed to have three ... unlike the two in http://, https://, ftp://, etc.). The next two are the first part of the unc path switched from back-slashes to slashes. HUGE CAVEAT!!! This will only work by default in Internet Explorer and only if the user is on the same network as the UNC path. Meaning, this will not work for a publicly accessible site. This will only work for an internal intranet-ish site. Only IE has the file protocol turned on by default. You can get extensions for Firefox and Chrome that will enable it.
