When I got my new PC in 2009, I put the whole of the contents of the old computer's hard drive in a new folder on my new PC. On the old computer running Windows XP, I used Outlook Express for E-mails. The OS for the new computer was initially Vista since upgraded to Windows 7 so my ISP recommended Thunderbird for E-mails and I didn't worry about losing all my old E-mails and didn't export them to Thunderbird. Now I'd like to have a look at my old E-mails and their attachments. They must be lurking somewhere on my computer (perhaps in a file I found called LostMail.dbx of 46 Mb). Is it possible to uncover my lost E-mails?
