Another thought/question just occurred to me ....

We would, of course, make a backup of our current company file before we started creating a new one and again before we started using the new one. Since we had a backup with all the prior history, is that a file we could access if needed to help in some research or problem solving? If the login was restricted to one login (other than admin) that had only inquiry rights, it would seem to me to be a valuable tool to have. Not for any input or activity, just for viewing  ...????
