If someone shares something with you in Google Drive, you can and should add it to your Drive. You must first check or highlight the item you wish to add to your drive. Then select "add to my drive" It will look like this:
New Drive View:
Old Drive View:
If it is an item the person who shared it with you may delete and you want to make sure will ALWAYS be available to you, ask them to make you the owner of the item.
You can also "make a copy" and then the copy will be in your drive as "Copy of..." but you will be the owner.
Google "how to __________ google drive" and you should see directions or stop by and I will show you how. It's super easy and doesn't take long.
