Overview

Mail Summary File, or MSF, is a file type accessible with the Thunderbird email program. It houses the heads of emails as well as the synopsis. The Thunderbird email software saves emails in the file formats MBOX and MSF. Whereas the MSF keeps the index of the particular letter being kept, the MBOX retains all the elements of emails. The MSF file format guarantees that other programs may import emails from the MBOX without requiring further outside third-party tools.
