How to Bulk Extract File Attachments from .EML Email Files

Software screen image showing how to select email file attachment extraction.

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 (or you wouldn’t be reading this article).

A faster and much 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).

Bulk Extract File Attachments From .EML Files

For people who have work to do with email content, EmlViewer Pro, is a helpful tool that delivers many specialized functions. Some of these functions are very specific, and are not used very often, but when you need them it’s good to know they are there.  

One of the special functions is the ability to process a large number of .eml files, extract email file attachments, and save them outside of the email in a single folder where they can be indexed and easily accessed by the Windows operating system.

Let me rephrase that last paragraph slightly for clarity. Although I said it will “extract” file attachments from .eml files, in practice that’s actually not a 100% correct statement. Here’s why:

EmlViewer Pro will not actually delete or remove the file from within the .eml file. Rather, it will create a copy of the file attachment and save it to a folder you designate.  The file attachment will remain within the unaltered .eml file; only a copy of the attachment will be stored in a Windows folder. EmlViewer Pro operates this manner to to preserve the integrity of the original email. It will only read email files (including .msg, .eml, .pst, .ost files), and it will never modify or otherwise alter the original message.

Select the messages in the list that you want to process. Selected emails are highlighted. To select all of the emails in the list, click on the first email and then type “Control-A” on your Windows computer keyboard. You could also select a range of emails by holding down the shift key and and clicking the first and last emails in the desired range.
