Description
MSG file extension is a product of Microsoft for messaging in Outlook mail. It was developed for the management of emails communication for Microsoft users. A MSG file is created every time a message is written using Outlook. It has information that is of importance from the message sent through email and details about the message. Programs that open such files are usually compatible with the Microsoft Messaging Application Programming Interface.
Technical details
MSG file is a complex text file but contains all the information and cannot be viewed using Note pad or other word processing programs. A binary format is used in the creation of the message and compatibility with programs depends on whether it has a MAPI system. This unique file format makes it impossible to import to other email services. The creation of this file format is automatic upon execution of a function, for example saving a message.
