Reinstall Eudora 8 after xp install when I have four folders of e-mail

I have recently had to reinstall Windows XP. I have five folders of e-mail created with Eudora 8. The last time I had to reinstall Eudora, I wasn't able to access all the folders. The folders are: E:\Eudora_Mail\David E:\Thunderbird\Profiles\kva8dxel\default\Mail\Local Folders E:\Thunderbird\Profiles\kva8dxel\default\Mail\pop.ca.inter.net G:\Local Folders G:\pop.ca.inter.net I suspect the folders on G: are backups of the folders on E:\Thunderbird, but I would like to access them to confirm that. I would appreciate any suggestions on how best to do that. Or possibly how I could transit to Thunderbird and have access to all of these folders.
