An exe file (pronounced as letters E-X-E) is a computer file that ends with the extension ".exe" otherwise known as an executable file. When one clicks on an exe file, a built-in routine automatically executes code that can set several functions into motion. Exe files are used to install and run programs and routines.
An exe file is just one of several file format types that are recognized by various operating systems. Text files, which are files that do not generate code but simply display text, end in txt. Microsoft Word saves files with the doc extension, short for document. Another common file type is the compressed or zipped file, which uses the zip extension.
The exe file is one of the most useful types of files precisely because it runs programs; however, this also makes it potentially harmful. It can be used as a delivery system for viruses or other malicious routines. Outwardly, the infected exe file might seem quite benign. Clicking on it might appear to launch nothing more than an animated cartoon or simple arcade game. However, unseen code can be running in the background, infecting or compromising the computer.
