Files that contain the .eml file extension are email files that have usually been sent or received by a POP3 email application. These files are normally associated with the Outlook Express software, which is a POP3 email application that is distributed by Microsoft. In some cases, however, EML files can also be created by other email clients as well.
The EML files contain the contents of an email message and they may also contain attachments that were sent by the sender with the original email message. EML files can also contain hyperlinks and linked attachments.
EML files are normally stored in plain text format.
