I copied Thunderbird folder in on my old computer to thumb drive. I Installed Thunderbird on new computer. I replaced the Thunderbird folder on the new computer with the data from the old computer. The folder on old computer had over 9,300 files. I ran the Thunderbird on the new computer. The old mail data was not shown. I was asked to create and new mail account the new computer. Mail from old computer did NOT appear. What is needed to get all of my mail, addresses and calendar data to the new computer. A large number of files are in the folder. see a sample of the names are attached,

thanks
