End User Guide
Files and media
Upload, download, view, and remove files while server-side access checks, encryption, range requests, thumbnails, retention, and audit records protect file workflows.
View and download
Images and videos can be viewed inline where the client supports it. Downloads support range requests so large media can stream efficiently.
Remove files
Senders can remove their own file attachments where the UI exposes that action. Retention policies can also remove old attachments. In both cases, chat history keeps a tombstone so recipients understand that the item was removed.
