Drive file suggestions in Chrome allow users to search their Google Drive files directly from the Chrome URL bar, instead of drive.google.com. Users can search for any Drive files that they have access to, including ones they haven’t previously opened in Chrome.
Starting December 16, 2019, Drive file suggestions in Chrome will be enabled by default for all G Suite users. If an admin wants to prevent drive file suggestions from being used in their organisation they can disable the “Allow Google Drive file suggestions for signed in users whenever a search is performed” in the admin panel.
If you leave Drive file suggestions in Chrome enabled, users who are signed in and opted in Chrome sync will see Drive suggestions in the Chrome URL bar for their synced account (Chrome version 69 and above). To learn what sync settings users can manage and how they’re managed please contact Myrtec or view the Google Help article.
