MBOX is hard to read, print or file as it is

RFC 4155 defines MBOX as many messages in one file, and the Mozilla Thunderbird Maildir page calls it the traditional Thunderbird format. A big MBOX opens only in a mail client, and printing from there is slow. MBOX to PDF converter reads the MBOX on Windows and saves every email as a PDF, with your MBOX left as it was.
