How do I send a link using Google Drive to someone who doesn't have a Gmail account?

1. Create folder.
2. Right click on folder. Select “Get Shareable Link”.

You will get a dialog box like this:

The link is automatically copied to your clipboard, so all you need to do is go compose an email, and paste the link into the body of it.

That’s it. The recipient can save the email, or save the link to a note or something… They just click the link and anything in that folder will be available to them. No Google account needed, anyone with the link can access.
