Q:  After collecting data for 3 years, I find my dat files become very big and hard to manage.

A: In db.robot.c you will find just the functions needed; Split and Backup. Under File menu, choose Split to split your dat files into year files, after being splitted there are individual dat files for each previous year, the current year is intact. Then run Backup which will make a copy of all marked dat files included Split files to a new location, e.g. to any computer found on your network. This will run automatically once set up and save you lot of trouble of doing backup work.
