I have two Macbook Pros in my office. I would like to send a link to a file (specifying its path) to another user, using that other MacBook Pro. We have a commonly mounted network drive. So I would just like to send the link to the file I'm asking her to reference. I can see that the 'add link' feature lets people attach URLs. But what about these semi-private files on the local network?
In most cases you can drag a file into a terminal window to get the full path and that would be something you could paste into an iMessage window.
If you want it to be a true link to the file, prepend the path with file://
