What Are MBOX & EML Files?

MBOX Files: MBOX (Mailbox) is a file format used for storing email messages. It’s a plain-text format that organizes emails into a single file, usually named “mbox.” Moreover, these files store multiple email messages as concatenated text, separated by special delimiters. Each email begins with the “From ” (with a space after “From”) line, signaling the start of a new message. In fact, it is commonly associated with Unix-based email clients like Mozilla Thunderbird, Apple Mail, and some versions of Microsoft’s email clients.

EML Files: EML (Electronic Mail) is a file format that stores a single email message. Each email is saved as a separate file with the “.eml” extension. In addition, these files are typically plain text or MIME (Multipurpose Internet Mail Extensions) format, containing the email’s headers, body, and attachments. Moreover, such files are widely supported by various email clients, including Microsoft Outlook Express, Windows Live Mail, and other applications.

In summary, MBOX and EML serve distinct purposes for email storage. Now, we will learn the conversion process from MBOX files to EML format.
