- Scroll to the bottom and click Next step.
- Keep the default settings (Destination: Send download link via email | Frequency: Export once | File type: .zip).
- Click Create export.
Note: Google will take anywhere from a few hours to a day or two to prepare your file, depending on the size of your inbox.You will receive an email with a download link once it's complete.
