What is an .AS file?

The as file extension is associated with Adobe Flash and used for so called ActionScript documents.

ActionScript is a scripting language based on ECMAScript. It is used primarily for the development of websites and software using the Adobe Flash Player platform (in the form of SWF files embedded into Web pages), but is also used in some database applications (such as Alpha Five), and in basic robotics, as with the Make Controller Kit. Originally developed by Macromedia, the language is now owned by Adobe (which acquired Macromedia in 2005).

ActionScript was initially designed for controlling simple 2D vector animations made in Adobe Flash (formerly Macromedia Flash). Later versions added functionality allowing for the creation of Web-based games and rich Internet applications with streaming media (such as video and audio).


An as file extension is associated with the Adobe Flash for Microsoft Windows and Mac OS X operating systems. An as file stores ActionScript document.

How to open:

ActionScript files are common plain text files. You can view it or edit by any common plain text editor available under any OS platform.

How to convert:

Probably can be compiled to other formats.
