What is MSG file?

Files with the MSG extension are used by the Microsoft Outlook email messages program. This program, by creating an MSG file, stores in it all the most important information regarding an email message , including subject, content, sender and receiver data, date, and also hyperlinks and attachments.

When is MSG file created?

System generates an MSG files always in the moment when an email message is being stored or created in the Outlook program. However, the file can be generated also in other circumstances – not for an email message but for the special tabs in the Outlook program, such as schedule, contact or task. Of course, it appears after introducing changes to one of the above mentioned tabs.

Opening MSG files

MSG files can opened only by these programs which support the MAPI interface (Microsoft's Messaging Applications Programming Interface). It result from the fact that the MSG files are not stored in a simple text form, but in a binary format, therefore their import is a bit difficult. Exporting MSG files is possible mainly in order to archive them, store or scan with antivirus programs.
