I had thought that simply copying the data file and putting a copy of it into our new annual phone directory folder would allow me to save last year's database unchanged as I create the new one this year. I discovered that this does not work. All changes made in the new copy of the database are reflected in all of the old ones as soon as I make the changes.
What is the easiest way to create "this year's" database and keep last year's unchanged? Is it necessary to use "Create a New Database" in the File Menu and do imports of all the old data, and then make the changes?
