You can definitely download all of the files in your account, and with one command in the API.  I have done it in the past, at least.  I don’t recall exactly but I think it was a “get” command of some sort.  You can download hundreds within a very short time.   What I am trying to figure out though is if a brand admin is able to download all of the instrumentation (not record data) from our entire brand.   We have a leader who feels that a summary of all surveys we have used would be helpful in governance.   It’s possible, but I’m a bit doubtful that it would that useful except as a way to look up individual items because it would be extremely challenging to analyze in any meaningful way the resulting data).
