Prevent editors from re-sharing and changing access permissions""

If you’re sharing a file, the owner and anyone with editor access can change the permissions and share the file. To prevent others from sharing your file:

  1. Open the file in Google DriveGoogle DocsGoogle Sheets, or Google Slides.
  2. Click Share or Share Share.
  3. At the top, click Settings Settings.
  4. Uncheck Editors can change permissions and share.
Important: If you prevent sharing of a folder, it only applies to the folder. To prevent sharing the files inside, you have to change this setting for the files inside.

When someone with Editor access tries to re-share a restricted file or folder, they get an option to email you for permission to share the file. You can decide whether to share the file. If you do, the user still can’t change access permissions. They’re grayed out and not available.
