File extension msf is associated with Mozila Thunderbird. Thunderbird's mail files are in the standard plain text "mbox" format, which almost all mail programs can use or import.
Many proprietary mail programs have a function to import from Eudora, which also uses the "mbox" format; this function should read your Mozilla mail files properly.
Your mail files are inside your profile (see the Profile Folder), in the Mail and (if you use IMAP) ImapMail folders.
Each mail folder (Inbox, Sent, etc.) is stored as two files — one with no extension (e.g. INBOX), which is the mail file itself (in "mbox" format), and one with an msf file extension (e.g. INBOX.msf), which is the index (Mail Summary File) to the mail file. Tell the other program to import mail from the file with no extension.
The *.msf file is used by Thunderbird for internal purposes.
It doesn't seem very likely that conversion of any kind is possible for this type of .msf files.

File can combine multiple sequences in a single file, called a Multiple Sequence Format (MSF) file. MSF files include not only the sequence name but also the sequence itself, which is usually aligned with the other sequences in the file. You can specify a single sequence within an MSF file, a subset of sequences, or all sequences.
Use compatible tools to work with *.msf files.
Probably can be exported to other formats.

The msf file extension seems also be used for some kind of list file generated by certain Sony recorders, for example the PCM-D50. You can these lists as MSGLIST.MSF files.
The msf file contains information such as the order of folders, playback order of audio files and recording date and time.
If user connects the recorder to the computer, the MSGLIST.MSF files are displayed, but you should not delete or change these files. If these files are changed, they may get broken or the recorder may not work correctly.
You probably cannot access these files manually.
A conversion of any kind of highly unlikely.
