The .pdf file or document that was saved to disk is not on the disk. I have not been able to find it using multiple search variations, and therefore the computer could not find it either. There would be two reasons for this:
1. The .pdf file that was saved got diverted in transit to someone else. If that is the case then I can assume that there is a witness. I shall take the opportunity to exaggerate this in my thinking to confirm that there are many witnesses. Perhaps he or she will profess words in English on the news in due course.
2. There was some discrepancy in the technical process.
