In the new Drive UI, under Users audit, we have added a tab called Drive Productivity.
Once it is selected it shows the Drive Productivity for each individual user in the domain.
It shows all files owned by the user, the number of Public, Public with a link, Shared out, Internal, Private, G Suite docs, spreadsheets and presentations created/updated last week.
All this information is available just by selecting Drive productivity tab.
The user can apply different filters on the top and gather different information and even schedule a report on the activities of the users for a certain period of time.
For example, you can schedule report for all users who created G Suite docs greater than 100 and generate a report every weekend.
The general purpose of scheduling reports is to show user engagement with overall Google Drive environment.
