There are two ways to add a file:

  1. You can attach a file by selecting the paper clip icon at the left side of the message field in a conversation or room, browse to the relevant file and select to upload.
  2. We also support drag & drop; select the file from your desktop or a folder and simply drag it onto the message field .
You can either just send the file or you can also add text to the message field with the file.
