How to delete a message (an attached file) from chat ? (after 6 hours)

one of our users share a big folder (5Gb) in Talk and we can’t find how to delete the message (and the big folder) .

Could anyone explain us how to do this please ?


Every file shared into a talk room is a share of that particular file/folder. So just go to the files app, open the Talk folder and look for the big folder you’re talking about. Then unshare that folder.
