What Is an MSG File?
An MSG file is a compound binary file format created by Microsoft. When you drag an email out of Outlook onto your desktop, Outlook stores that email in the MSG file. Inside the file it stores the following:
- The Message Body: The text that you read.
- Headers: Technical details like the IP address of the sender.
- Metadata: Information such as the Sent time, Subject and From address.
- Attachments: All the PDFs, images, or documents that were sent with the email.
It is difficult to open a MSG file without Outlook because it is written in binary language. Your computer’s Notepad or TextEdit app cannot read this language so they show you unreadable data. If you want to know how to open MSG files without Outlook, you can read this.
