Is it possible to set permissions so the file is
You can set the permissions for link access in a similar way to the previous answer.
From the sharing popup - click
advanced. This adds a row for public access, set to
off by default. You can click it to access the
Link Sharing popup in which you can set it to be publicly accessible to those with the link. Once you've turned link sharing on a drop-down appears to select what public users can do - either view only, view and comment or full edit access.
