This is a new feature of the job board that we added because of GDPR requirements. It is generated when a candidate logs into your job board and clicks on the "Download My Record" link under the preferences tab. This link is hyperlinked to a zip file containing a spreadsheet of the candidate data and a spreadsheet showing what jobs were applied to.
