Understanding EML Files

What is an EML File?

An EML (Email Message) file is a file format used by various email applications to store the content of an email message. The EML format is plain text and typically includes the email's subject, body, sender and receiver addresses, date, and attachments (encoded in a way that is compatible with plain text).

History of EML

The EML file format was originally developed by Microsoft for its Outlook Express email client. Over time, other email clients such as Mozilla Thunderbird and Apple Mail adopted the format, which has led to its broad usage across various platforms.

Common Uses of EML Files

• Archiving: EML files are commonly used for email archiving due to their plain text format, making them easy to store and retrieve.
• Migration: Many users export their emails as EML files during migration processes from one email client to another.
• Backup: EML files serve as an effective way to back up important emails without needing a specific email client to access them.

How to Open EML Files

EML files can be opened by various email clients and applications. Here are a few popular options:

• Microsoft Outlook: Users can drag and drop EML files into their Outlook application to view the contents.
• Mozilla Thunderbird: This open-source email client natively supports EML files.
• Windows Mail: The Windows Mail app supports EML files, allowing users to open emails directly.
• Web Services: Some online services and converters allow you to view or convert EML files to other formats, such as PDF.
