The most common filename extension denoting an executable application is EXE, and these files are also known as Windows Executable files.
Any item that has this format should launch when it is double-clicked by the user (otherwise, it means it is corrupt).
A lot of installers have this extension and they will start the installation process once they are double-clicked, without requiring administrative rights.
EXE creators will allow developers to build their own installers containing their applications and the corresponding documentation.
One can also built EXE installers by converting files of other formats to EXE using specialized applications.
