# dataSources.files

List the files attached to a row or page: files in file columns and files embedded in the page. For google_drive, itemId is a folder (its files, partial when there are more than 200) or a file (itself); Google Docs, Sheets and Slides are listed as PDFs. With target, files already imported there are marked. File download addresses are never returned.
