Change to the drive and directory where the cost update is installed. Double click on the name of the user costbook you want to open. Changes to that costbook will appear in red and the file name will appear at the lower right corner of the costbook window. The current version of National Estimator will open estimates that have been created in earlier versions of National Estimator, even the old DOS version of Estimate Writer. To save, just click on the Save button.
Saving takes only a second or two.
If a power failure or some other problem wipes out an estimate, open the backup. National Estimator creates backups automatically when you save over any existing estimate. To open a backup, click on File, Open. Under List Files of Type, select Estimate Backups to see the backups available. The procedure is explained in Help.
