how tails files used and why tails server url public

[abhimin]

I set the tailsserver and revoking the credential.but need some info on how the tails file in storage path used and why tailsserver url should be public.
Is it safe to expose tails files to Internet and who are interacting with tails server.

Please share some insights on this.
