What is an .AS file?
AS files are source code files written in ActionScript, a programming language developed by Macromedia and later Adobe for creating interactive content in Adobe Flash. They contain instructions that control elements such as animation, user input, buttons, multimedia, and other interactive features in Flash applications and websites. Different versions of ActionScript were used throughout Flash's history, with ActionScript 3.0 as the final major version.
You may come across AS files when examining an older Flash project, maintaining archived interactive content, or working with source code from a legacy Flash application or game. They may be stored alongside FLA project files, graphics, sounds, and other assets used to create Flash content. File Viewer Plus can open, edit, and save AS files, making it useful for viewing and modifying ActionScript source code.
