You can also share entire folders within your Google Drive. The advantage of sharing an entire folder is that all Documents and files within that folder will be shared with the people that you choose. Also, any new Documents or files that you create in the shared folder or move into that folder will automatically be shared.
There are a number of different ways to share a folder, but here's the most straightforward method.
Any Documents or files that are moved into the shared folder will automatically inherit the sharing settings of the folder. This makes it simple to share Documents and files with specific or groups of people (colleagues or students).
