For a file, the URL syntax would be file:// as in file://c:\mypicture.jpg, assuming that .jpg files are associated in Windows Explorer (Tools | Folder Options) to always open in your image editor.
To open a file in a particular application without that association, you'd need to write script that uses the syntax appropriate to that application.

Hi,
I have one problem to ask. When I type http://google.com in outlook it
appears as link, but when I type only google.com it does not appear as link.
I want to know what determines this? I have a requirement to make a shortcut
link for opening some file in my image editor. I want to make link like this
clicking on which the file opens in my image editor. Any clue? I guess it can
be done by thinking in direction “how does a file say .doc file is associated
with MS Word”.
Regards,
Rajeev
