The 'Data and Settings Transfer Wizard' allows you to back up and transfer all your Messages, Contact, Settings and Content. This will allow you to restore your data and settings after formatting your computer, upgrading your Operating System, or changing to a new computer. It's a good idea to back up your data regularly.
Your IncrediMail data will be saved in sequential 700MB files; if your data exceeds this amount, IncrediMail will create several files, which will need to be saved and/or transferred together.
