What does the .exe file extension signify?

The .exe file extension signifies an executable file in the Windows operating system. This type of file is a program or application that can be run by the user by double-clicking it. When executed, an .exe file will initiate the program it represents, loading it into the computer's memory and allowing it to perform tasks or operations defined in its code.

Executable files typically contain compiled source code and operate to perform various functions, such as installing software, running applications, or carrying out scripts. Understanding the role of .exe files is crucial in the context of computer security, as they can potentially contain harmful malware if sourced from untrusted origins. Thus, users should exercise caution when executing files with this extension.
