You should see a number of .dbx files and possibly some other files, too.
After locating the email folder, you can simply select all the files and press Ctrl-C. Then open the folder where you want to keep the backup copies (on another hard disk, a DVD or a network drive, for example) in Windows Explorer, and press Ctrl-V. To backup the Address Book, you can follow these steps:
a.. Select Tools | Address Book... from the menu in Outlook Express.
b.. Choose File | Export | Other Address Book...from the address book's menu.
c.. Select Text File (Comma Separated Values) as the export format.
d.. Click Export.
e.. Select the location you want to export your address book to using the Browse... button.
f.. Give your backup copy a meaningful name.
g.. Click Next.
h.. Select the fields you want to include in your backup.
i.. Finally, select Finish.
j.. Click OK.
k.. Click Close to end the process (successfully, Ihope).
Additionally, there are several email backup utilities which can make the backup operation much easier. Outlook Express Backup Genie is one piece of software that can offer peace of mind by creating compact backup copies of emails, attachments, address book, signatures, blockedlist, mail rules and settings periodically. The difference between using a automatic email backup utility and manual backups, is that the first can be scheduled to create backups quiet in the background at specified time intervals, and that it will include all email information ( signatures, blocked list, etc ) which otherwise would be more difficult to save. Also if ever the backup is needed, the application will ensure that the restore process is made smoothly. And, it works with top 9 popular email clients.
The downside of using a automatic email backup utility is that it costs money, usually about 20-30 USD as one time payment, while the manual backups are ofcourse, free.The conclusion is that either manual or automatic,backing up emails is a critical operation for every computer user that would regret losing them.
