Private files
Non-public files are owner-only. Guests see a sign-in wall; other members get a hard private message. Schema default is private.
Private files
Files not marked Public cannot be downloaded by others.
Where to find it
/{fileId} (and /prep/...) for non-public files
How it works
File.isPublic defaults to false in the schema; new uploads may start public when Files public by default is on. Guests see Private file and a prompt to log in as the owner. Signed-in non-owners get a hard private message (no download UI). The owner can open and download while signed in (and passing any IP allowlist). /d/... for private files also requires the owner session.
Admin public overrides can force public/private for all of a user's files and lock member toggles.
Common problems
Shared a private link
Others never reach mint UI - set the file Public first.
Owner blocked by IP allowlist
You are on a non-whitelisted IP - see Whitelisted IPs / account help.
