.AUT File Extension

File used by AutoIt, a program originally developed to automate the setup of large numbers of Windows PCs; contains BASIC-like program code that interacts with processes and simulates keystrokes and mouse movements; can be used to create Windows GUIs.

AUT scripts can be compiled into stand-alone executables using Aut2Exe, which is bundled with AutoIt. AUT files are primarily associated with AutoIt v2.
