If you thought they removed the feature to add shared folders to your own drive, you can be relieved to know that it still exists!!!

In your browser, open up: drive.google.com

Navigate to the “Shared With Me” area (left column).

Select an item or folder (single click to highlight it).

Next use SHIFT-Z to activate a hidden menu that will allow you to add the item or folder to your own Google Drive.

THAT’S IT!

Enjoy.
