Hi Ross,
Thanks so much for clarifying. It sounds like we'll be doing a full pull of the metadata and ACLs regardless, since the API does not provide a way to narrow the result set based on the shared status. That was my assumption after looking at the docs, but it never hurts to ask the experts. :-)
On a related note, I tried to limit the results by using various other search terms, but most seem to fail. For example, I tried limiting the search to files created after a specific date and got this:
$ gam user dparker show filelist query "createdTime >= '2022-02-01T00:00:01-05:00'"
Getting files for dpa...@utica.edu...
ERROR: 400: Invalid query - invalid
Got 0 Files for dpa...@utica.edu...
