Chat archives
A chat archive is a single-conversation ZIP. Use it for long arcs, device migration, or sharing. Not interchangeable with full backup ZIP files (full vs single-chat packages).
Path: Settings → Data management → Chat archives.
Export (create archive)
Export packs messages, session settings, and related local assets; the ZIP is saved to the in-app archive list and can be shared when done.
