An executable file (Exe file) is a computer file that contains an encoded sequence of instructions. The system can execute directly when the user clicks the file icon. The Executable files commonly have an EXE file extension, but there are hundreds of other executable file formats. Some executable files can run on any compatible system without the existence of another program. Such files, which are considered to pose a high-security risk, include EXE, BAT, COM, CMD, INF, IPA, OSX, PIF, RUN, and WSH.
