To download attachments from an *.eml file manually, you can open the file in an email client like Outlook or Thunderbird, then open the email and save the attachments individually. However, this process can be time-consuming, especially for multiple emails.
Alternatively, you can use Advik EML Converter to extract attachments from *.eml files in bulk. This tool simplifies the process and saves you time by automatically extracting attachments from multiple *.eml files at once.
