How to Bulk Extract File Attachments from .EML Email Files

Email messages are often stored or archived as individual EML files. They contain the email message, sender and receiver information, the internet header data, and any file attachments that were appended to the message.

What if you have a directory filled with hundreds or thousands of  EML files and you want to save a copy of all email file attachments to a folder on your hard drive? 

One way to do it would be to open each .eml file individually, and extract the attachments manually. This labor intensive method doesn’t appeal to me, and probably not to you either or you wouldn’t be reading this article.

A faster more efficient method to bulk extract file attachments from EML files would be to use the “Only Attachments” export operation found in EML Viewer Pro email viewer (download a free 15 day trial).

EML Viewer Pro is a viewer for email content including EML, MSG, PST, OST and MHT files. In addition to accurately rendering your emails, it allows you to perform useful tasks, such as searching, print, exporting to PDF and other formats, and even Reply and Forward our .eml email messages.

To extract file attachments from EML files with EML Viewer Pro, start the software and select the folder containing your .eml files.

In the email list, type CTRL-A to select all of the files.

Select “Only Attachments” from the Export Profile setting, and click the Export Button to start the process (the export button is the green down arrow).

Usually, EML files are opened individually. Click on an .eml file and it will likely open in your default email client. However, if you want to be able to manage and search a quantity of .eml files, then you should take a look an email viewer like EML Viewer Pro.
