EML files are text files containing one message per file, and message attachments are normally encoded within each text file. The EML file can be viewed in programs such as Outlook Express and Windows mail. These files are based upon the RFC-822 single email standard.
- No email client is required for conversion.
- The data file normally has the .EML file extension, but you may also find these same RFC-822 single emails with the .MSG file extension (those MSG files are different than Microsoft Outlook MSG files).
