Backup Your MileTracker.settings File Occasionally
A couple of days ago MileTracker unexpectedly told me that I had no mileage or hotel programs set up! Fortunately, I found a MileTracker-Backup file on the computer in the same folder as the MileTracker application. I made a copy of it, then renamed the copy to MileTracker.settings and didn't have to type in all that data again.
I plan to be more careful to make regular backups in the future. It's easy to do -- just pull down the Setup menu and click on "Backup Users, Accounts and Options."
