Basecamp 3 Help

Hi everyone, I am a fairly new user, but have several projects I'm in on this platform, so I decided I should learn more about the features. I was trying to see if documents attached to messages in the message board were uploaded to the docs and files folder, and they are not. I wish that was a feature option, but have not found it yet. So in the meantime, I will try to capture the attachments and put them into the resources folder for future reference. If you are interested, I found the help site to be useful: https://3.basecamp-help.com/
Happy Friday ya'll!
