You'll need to install Google Drive File Stream
Google Drive File Stream provides access to your Google Drive account via File Explorer (the yellow folders you've been using for years...like the C: Drive, etc)
Once the Installation file finishes downloading, click on it to begin the installation.
Once installed, login with your email address and password, then click through the brief tutorial.
You now have a G: drive to access your Google Drive files. (You can save Microsoft Office files directly to your G: drive or drag folders into your Google Drive or Shared Drive)
