File with EFI extension is a system file used by computer systems and devices based on Intel architecture, for example, AppleTVs. EFI file contains data executed between operating system and firmware levels.
EFI system files are used during system boot process, for staging firmware updates, and running pre-boot programs. EFI files allow system to hand-off pre-boot processes to the controlled environment. Sometimes EFI files are included in firmware update files and loaded into EFI during the boot process.
EFI standard was initially developed by Intel. Next, EFI was updated and became known as UEFI (Unified Extensible Firmware Interface) standard, which is to replace legacy firmware interface Basic Input/Output System (BIOS).

There can be more reasons which determine that you are not able to open the EFI file (apart from the lack of the proper application installed).
First - the EFI file may be incorrectly associated with the application installed to support it. In this case, you need to change this association by yourself. To do this, right-click on the EFI file that you want to edit, click "Open with" and then select the program from the list that you have installed. After this operation, the problems with opening the EFI file should be solved.
Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version of given file, or download it again from the same source as before (maybe for some reason in the previous session the download of the EFI file has not been completed and it cannot be opened properly).
