right, so i'm about to do a clean install of XP Pro using an XP pro upgrade. i've backed up important files, and some install programs. so to format my drive, all i have to do is go to "c:\windows" and type in "fdisk"? and it'll go go go? and when i put back my saved files, say, emails, i just need to know the folders where they are kept, and just paste them there, and nothing bad will happen, and i'll find all my emails as i left them? or do i need to set up the email addresses before i do that?
