If your email is in HTML format and you include a <a> tag where the href is set to file://somepath; I'm pretty sure that when the user clicks that link the browser will "hand off" the complete path to the operating system and ask for the file to be "opened".
If that path points to an existing file and the computer that gets the email has a file association for the filetype of the file, then that program should run (possibly with a warning from the browser about not running links from emails). For this to work, all the following has to be true: 1. The link in the email must point to a file visible to email's recipient. That means the recipient will have to be on the same LAN as the file and that the file path should use UNC notation rather than a mapped drive (or that you're absolutely certain that the file your pointing to is on the same location on every user's hard disk). 2. The recipient's computer must have a file association for the linked file. 3. The linked file must be runable. So, if you include something like <a href="file://your_server/share_name/rbase_programs/start_program.bat">Click to start</a> you may be able to get this to work. -- Larry
