Windows context menu option for "Copy a link to file"

Windows context menu option for "Copy a link to file"

Is there a utility to add a context menu option for copying a link to a
file to include in a plaintext email (or something that accomplishes the
same thing in Outlook) for Windows 7?
For example, if I have a mounted Windows network share \\foo and there was
a file on it bar baz, I would like to get file:///\\foo\bar%20baz. Ideally
this would work with mounted FTP drives, etc., but what I really would
like it for is network shares.
Shift-right click gives a "Copy as path" option, but this will generate a
path like "Q:\bar baz", not file:///\\foo\bar%20baz. Outlook has a link
function, but it does not work with plaintext email.
