Notes about the ACTIONSCRIPT file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The ACTIONSCRIPT file type is primarily associated with 'Flash' by Adobe Systems Incorporated. Adobe Flash, initially known as Shockwave Flash and popularly called simply Flash, refers to both the Adobe Flash Player and to the Adobe Flash Professional multimedia authoring program. The Flash Player, developed and distributed by Adobe Systems (which acquired Macromedia in a merger that was finalized in December 2005), is a client application available in most common web browsers. ACTIONSCRIPT files contain ActionScript source code in simple source files. FLA files can also contain Actionscript code directly, but separate external .ACTIONSCRIPT files often emerge for structural reasons, or to expose the code to versioning applications. They sometimes use the extension .AS.
