What is an .AU3 file?
AU3 files are scripts written in AutoIt, a Windows-focused scripting language designed to automate repetitive tasks and simulate user interactions. They contain commands that can open applications, click buttons, enter text, manage windows, work with files, and perform other routine operations. Scripts can also use variables, functions, loops, and conditional statements to handle more complex automation tasks.
AU3 files often appear in Windows automation projects, utility scripts, software installation routines, and tools that simplify repetitive desktop work. You might encounter one when downloading an AutoIt utility, examining a script shared by another user, or maintaining an automation project. File Viewer Plus can open, edit, and save AU3 files, making it useful for reviewing or modifying AutoIt script code.
