After you set up and save a workbook, you can save it with a different name. Saving an existing file with a different name preserves the original, pristine copy of the file. For example, in the office, you might create an expense report or budget and then save subsequent updates to different filenames. Or you might use different versions of a workbook for forecasting or modeling. Later you can easily delete the versions of a file you don't need.
In the next To Do exercise, you save the Practice Save file with a different name. The Practice Save workbook should be open and visible on the screen from the first To Do in this hour.
