Email messages don't take up much space on your computer. The average message in my mail box is around 5KB (don't worry if you don't understand KB, I'll make it straight forward). Most computers purchased in the last 2-3 years have at least 20GB of disk storage. That being said, it would take about 200,000 messages to use up just 1G of the 20G your computer has. You'll buy a new computer before you fill this one up, don't worry about it. If you still need to do this, please let me know what program (Outlook, Eudora, etc) that you are using for your email so that I can give you a more specific answer.
