In private and mixed knowledge bases, a direct link to a file stored in Drive relies on a temporary access token with a bounded expiry window. This makes it hard to reference one specific file in an external channel such as email, where the recipient may open the link well after it was generated.

Suggested Enhancement: Allow an individual Drive file to be shared through a persistent, revocable link — similar to the existing private-article-link mechanism — so a recipient can reach that one file directly, without needing an article built around it and without the link expiring on a short, fixed window.

Benefit: People could share a single document, such as a policy or template, through a link that keeps working whenever the recipient opens it, without first restructuring the content into an article.
