An EFI file contains interface for platform firmware and operating system. EFI files define booting environment and run pre-boot apps. Typically, EFI files are not openable. Advanced users can open EFI files with EFI Developer Kit, a cross-platform tool.

EFI files are UEFI boot loader executables. They have data on boot process. Open EFI files with EFI Developer Kit. This explains what an EFI file is for and how to open one if needed.
EFI files transfer pre-boot to controlled environment. For example, EFI files sometimes included with firmware updates. Executable content performs update procedures safely.
EFI Developer Kit may not handle EFI files if software outdated. Updated versions implement newer formats.
Files with .EFI extension contain system data of Intel devices like computers and AppleTV. Used when communicating between operating system and device software like loading operating system.
