Opening EFI files

Did your computer fail to open an EFI file? We explain what EFI files are and recommend software that we know can open or convert your EFI files.

What is an EFI file?

Files with the .efi extension are most commonly associated with Extensible Firmware Interface files. These files define the interface between platform firmware and a user's operating system. They create the environment for booting the user's operating system and running various pre-boot applications. The .efi file extension is also used for Microsoft Windows 7 files.

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
