Go to "Tools" and select "Preferences". Click on the "File" tab and at the bottom is "Log Changes". When this is checked, PAF will log your changes to the file indicated. Click on "View" and the log will give you the individual's RIN and the date that the record was modified. You then simply export these few records instead of your whole file. (One small problem that I have just discovered is that it also logs a change when you have looked at an individual's record but didn't make a change.) I hope this helps.
