How do I link to the file without it being public in the first place? I&#x27;d want it to not be publicly accessible, but only accessible through the purchase.<p>If the link is just hidden that doesn&#x27;t really solve the security risk of someone downloading the file from the public dropbox url or wherever else.<p>Perhaps they store the file on their server and you can unlink the file from your own server? I doubt that is the case though.
