Did someone email you an EML file that you don't know how to open? Do you have old EML files on a backup drive that you need to open in a specific program? When you want to open an EML file in Windows, there are a few things you can try. You can either open the email program first and then open the EML file, or you can change a specific setting on your computer so that double-clicking an EML file opens it in the program of your choice.

Instructions in this article apply to Windows 10, Windows 8, and Windows 7.

Change the Default Program to Open EML Files in Windows

Windows gives you the option to pick which program will open an EML file when you double-click it. This method is useful if you always want the EML file to open in the same program.

  1. In the Windows Search box, enter default.

There may be several programs on your computer that open EML files. For example, you can use Mozilla Thunderbird to open the EML file instead of a Windows email client.
