Show Package Content option not available in High Sierra on a pkg file

I want to "Show Package Content" of a pkg file which is inside this dmg file : https://desktop.visio.renater.fr/scopia/entry/pic/ClientComponents.dmg

So I drag'n'drop the pkg file which is inside the dmg to the "Desktop" folder.

Then I right click on the pkg file and here is what I see :

Can you help ?

Solution 1:

The Show Package Contents is used to show the contents of an application. If you go to an application on you mac and right click on it, you get a menu and one option is to "Show Package Contents". This applies to apps.

There is a way to show the contents of a pkg file but you must do it using the terminal. Just type the following command: pkgutil --expand /path/to/package.pkg /output/destination/. A description of this is given here.
