Sharing files via Gmail, Calendar and other Google apps is getting better with enhanced Access Checker.
When you add Drive files to emails or event invitations, Google currently warns you if recipients or guests do not have access to those files. However, Google is updating the order of sharing options that are presented to you. Later this month, the warning prompt will display the option to share files directly with people who need access before the option to turn on link sharing.
Access Checker will be available for a variety of file types in My Drive and Team Drive. This security enhancement is the result of end user feedback and reflects how your suggestions can impact the development of Google tools.
