It's common to have trouble searching software that can open and manage EML files on a Windows PC. This is especially if you don't have an email client that properly supports the format. That's why it's usually easier to use a dedicated tool. From my experience, Softaken Free EML Viewer works really well for this. That you can open and read EML files without an external email program is possible with this simple tool. You can see sender and receiver, subject and any attachments without losing the formatting. It can also open multiple EML files, which is useful if you have large amount of emails to manage.
Another useful thing I like about it is that it's safe to use, so you don't have to worry about changing your source files.
