The file extension .exe is commonly associated with executable files in Windows operating systems. These files are specifically designed to be run as programs and contain compiled code that the operating system can execute directly. When a user double-clicks an .exe file, the operating system loads the program into memory and starts running it, allowing the user to interact with the application.

In contrast, the other file extensions mentioned serve different purposes: .txt files are plain text documents, .jpg files are used for image files, and .docx files are associated with Microsoft Word documents. These formats do not contain executable code, meaning they cannot be run as applications within the operating system. This distinction is crucial for understanding file types and their functionalities in a computing environment.
