Open .EML Format Documents With EML Viewer Pro Software

Documents with the .eml extension creep into our work and lives from many different vectors. This article discusses what these files are, how to open .eml files, and software to search and manage large quantities of them.

What are .eml documents?  

.Eml document files are emails that contain the message and any file attachments accompanying the message. EML documents have been part of the internet for more than thirty years. They are formatted according to an open standard published in 1982 called RFC-822. This standard put forward the rules that has helped software developers create interoperable email clients such as Outlook Express, Windows Mail, Thunderbird, and others.
