Gmail limits attached files to 25MB; anything over that is automatically placed inside Google Drive. You can go through the process by starting a new email in Gmail and then attaching the file you want to send. If it’s too large, Google will generate a link to it in Google Drive.
After you try to send your email, you’re asked to provide your recipient access to the file. By default, the file is available just for viewing. You can opt to allow the person to review or edit the file, but they would need a Google account to perform either action.
Once you set the permissions, send the email to its recipient. The person then clicks the link in the email to view the file in Google Drive. Google may limit you to 15GB for the free tier of Google Drive, but any paid plan will allow you to upload up to 750GB a day (though files larger than this will still go through), with an overall file limit of 5TB.
