Changing File Formats
Were you an early adopter of electronic faxing services? We were. Back then the fax came into your email inbox in a proprietary format. You could open the electronic fax with the software from the company that you had the e-fax service with. Like most people, we saved off these files (contracts, etc.) believing we could retrieve them in the future.
Wrong! Our e-fax service changed their software and we lost every e-fax document that we had archived and saved. The company did not provide backward compatibility and there was nothing we could do.
PDF/A as an Archiving Standard
PDF is the electronic standard for exchanging information. To avoid a situation like with e-fax, PDF/A standard adoption guarantees that everyone will be able to access their archived documents years into the future.
