Convert EML to DOCM in C# .NET

What is EML file format?

The EML file is a type of email message that includes both the message content and the email header information. It is an extension of the Mime (Multipurpose Internet Mail Extensions) format and is used in most email clients, including Microsoft Outlook and Mozilla Thunderbird. EML files are used to save an email message before it is sent and can also be used to archive emails. The EML file format is an XML-structured file that is used to store the header information, such as sender, recipient, subject line, and date, as well as the message content, such as body text, HTML, images, and attachments. The header information is stored in the header of the file and the content is stored in the body. The file is readable by both humans and computers, and can be opened in a text editor, such as Notepad or TextEdit. EML files are commonly used to transfer emails between different email systems. For example, when an email is sent from one email client to another, the email is usually saved as an EML file and then transferred over the internet. This ensures that the message is delivered properly. The EML file format is also used to store emails in an archive. For example, emails can be archived in an EML file and then later opened and read in any compatible email client. This makes it easy to keep emails organized and backed up. In addition to being used for email messages, the EML file format is also used by some applications to store log files, document files, and other types of files.

What is DOCM file format?

The DOCM file format serves as a specialized variant of Microsoft Word documents, tailored specifically for creating and saving documents that contain macros within the Word application. Unlike regular DOC files that are intended for basic documents, DOCM files cater to documents incorporating macros.

Macros, composed of commands and scripts written in Visual Basic for Applications (VBA), empower users to execute more intricate automated tasks and functions. They prove particularly valuable in streamlining processes and automating repetitive activities, such as generating charts and formatting documents.

By saving a document as a DOCM file, users ensure that the macros they have created are included in the file and accessible when opened by others. Additionally, DOCM files provide an added layer of user protection by disabling all macros when the document is opened by someone else. This safeguard shields users from potentially malicious macros that could compromise the security and stability of their computer systems.

Furthermore, DOCM files retain compatibility with various versions of Microsoft Word, assuring users that macros will function correctly regardless of the recipient’s Word version. This compatibility facilitates seamless sharing and collaboration on documents containing macros.
