Is there such a thing?

I currently have a Mac.

I have about 10,000 e-mails in the .eml format saved on Google Drive. I previously was using Windows 3.1, 95, 98, XP & Vista. Needless to say, I don't want to look at each e-mail & decide which to save & which to delete!

I have a HP mini-110 with Windows XP. I can import the e-mails into Outlook Express so that I can look at them but as I previously stated, I don't want to look at 10,000 e-mails.

Well, unfortunately, I'll have to look at all of them eventually!

I need a free conversion program that will batch convert my .eml e-mails into a format that can be read from within Windows, Mac & Linux. Since I have a Mac, I want a Mac-compatible program that will convert my e-mails.

A few years ago I asked the same question & IMAP was recommended. How do I convert from .eml to IMAP?

Is .mbox a universal format? I read that .mbox will convert all e-mails into 1 text file. I don't want that. Then I'd have to go thru & separate all of the e-mails.

So, is there a solution?
