RTG Bills, RTG Timer, and RTG Conflicts can create a backup of their data using the menu choice File > Backup. This menu choice starts RTG Backup, which actually creates the backup files. The data is written in a compressed form.

In order to restore the data from a backup, the program RTG Restore is required. You can start RTG Restore with the menu choice File > Restore From Backup in RTG Bills, RTG Timer, and RTG Conflicts.

RTG Upgrade downloads and installs free upgrades from the RTG Web site. Choose File > Upgrade from the menu.

You can get the latest versions of all three programs from this page.

Warning:
Please be very careful when using RTG Restore. The software will not prevent you from replacing good data on the hard disk with old data from a backup. It is up to you to use RTG Restore only when it is needed.

You can install the latest versions of RTG Backup, RTG Restore, and RTG Upgrade with one installation file.

Note: The file used to compress and decompress the stored data, polarziplight.dll, was licensed from Polar. Copyright © 1998-2002 Polar. It replaces the two files used previously, zip32.dll and unzip32.dll.
