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.
