I am going to completely re-format a hard disk drive and would like to save all of the e-mail addresses without having to re-keypunch them in. The internet service is MSN, and the PC's operating system is Windows XP. Are the e-mail addresses stored on the local hard drive, or on a Microsoft server? If they are on the local hard drive, what is the name of the file containing e-mail addresses? In general, what files should I save before they get wiped out by the re-format operation? After re-formatting, would it just be a matter of copying the file(s) back into the same sub-directory they were in before the re-format? I have already saved all of the key data files (letters, spreadsheets, etc.) but don't know what to do for the e-mails.
