The recipient of a ShareLink to a folder or file can forward that link to additional people.

If you want the link to only be used once, make sure you have the ShareLink option set to One-Time. You can also consider adding an expiration date so the ShareLink automatically becomes invalid on a certain date.

If you believe someone has forwarded the ShareLink to others and you want to prevent access, you can disable the ShareLink from all further use by:
  • Accessing the Existing Share modal and clicking on the trash can icon (Delete) for the ShareLink created
  • Accessing Share Management from the left navigation menu, locating the share under the Shares tab and clicking the trash can icon (Delete)
