I’m aware of various of uses for the file extension “msg”. The file command should narrow the possibilities.


Launch Terminal app, and enter the following command with a trailing space, and do not press return:

file 


That’s f-i-l-e-space.


Then drag the file you want to know about into the Terminal window, and now press return.


What does the file command tell you about the file?
