Is your feature request related to a problem? Please describe.

1. All attachments from all conversations appear in the same "Talk" folder. When dealing with lots of conversations, the number of files is very high.
2. The attachments are shared with many people, as single file shares. So the "Share overview" becomes too crowded and barely usable.
3. Could technicall help solving Opening viewer cycle through all share talk medias #3347 to view all attachments in the slideshow for a single conversation.

Describe the solution you'd like

• Store the attachments using one subfolder per conversation
• Use folder shares to share with all participants
• Offer to "unshare from self" when leaving a conversation.

Not sure what name to use for the subfolder. The room name is intangible and might change. But the room id is too technical.

Further benefits
It would also make it possible to sync files posted to specific conversations also instead of all.
It would also make it possible to add a button to toggle between the attachment folder and the conversation, for #1577

Further ideas

In theory it could even make it possible to auto-post a file to a conversation just by adding it to the folder (but needs to track what was already posted and duplicates, maybe too fancy and not useful...)
