Here are several simple storage management practices that can contribute to keeping your total storage use below the cap:

1. Free up photo storage.

2. Use Google's own file formats.

3. Don't add shared files to Drive.

4. Empty Google Drive trash.

5. Clean up Gmail.

6. Delete duplicate files.

7. Delete or relocate large and other files that are not needed.

8. Set up shared drives in your department or workgroup to share single copies of files rather than creating several copies.

9. Do not store personal files in your work space.
