Share “Make a copy” links to your files

Want to let people make copies of your Google Docs, Sheets, Slides, or Drawings files with a single click? Just make a simple change in the link you share.

Examples

• Create templates for files, such as Docs proposals, Sheets project plans, Slides pitch decks, Drawings flowcharts, and more. Your teammates can quickly copy them to keep your organization’s branding consistent.
• Allow colleagues to create personal copies of your files—such as presentations, reports, or designs they like—so they can adjust it for their own purposes.

How to,

1. In Google Drive, open the file.
2. Copy the file link from the address bar.
3. In Gmail, click  Compose​.
4. Paste the file link in the email and in the link, change edit to copy.
5. When your email is ready, click Send.

   Note: If you haven’t shared the file, you’re prompted to share it now.

6. When the recipient clicks the link in the message, they’re instructed to click Make a copy.

   They can then work on a copy of the original document.
