i am planning to reinstall Windows , but before i do i want to save my e-mail and internet settings( account settings for E-Mail, address book, bookmarks, etc). I dont know what to save or where to find it on my 'C' Drive. I use Firefox and Thunderbird and have an external hard drive to save the files to. II do not want to save anything else just the E-Mail and Internet stuff.
Consider using EA8, google for 'EA8 emails', they is a trial download, this will save all your emails, address book and browser settings (favorites, bookmarks, accounts), etc. You may then consider buying or try the latest Acronis True Image 10 which does a similar thing
