I have uploaded my Yahoo email to Thunderbird and have now downloaded that to my desktop as POP. I see various folders as both "Mail" and Imap in my Profile on the Mac, with various subfolders as per my Yahoo email. When I open the various files, which are in detailed folders in the Imap folder, they are only visible as complex Text files. Is there I can open them with Outlook or Word, or something else easier to understand? Many thanks, Charles
