MSF is a common file extension with different formats for programs. The two popular formats are Mozilla Mail Summary files and email index files. View contents by opening the 1 KB to 780 KB files in a text editor. The msf mail summary file format edits and saves emails appropriately. Associate the MSF file extension correctly.
MSF has 3 file types. One type is the mail summary file seen in Thunderbird. This contains headers and summaries without complete messages. MSF files lack messages as Thunderbird stores emails split in two. One file holds emails. The other MSF file indexes them so other programs easily import mail.
The key MSF file type associates with the Mail Summary format and Mork database-like format. Mork first appeared in Mozilla software, including Thunderbird, for indexing. Now Mork mainly indexes Thunderbird mailboxes and address books. The MSF file indexes a mailbox folder. Seen in Thunderbird mail directories, the MSF file names match folder names.
