On a project we had a bunch of old interactive forms made with Flash and Actionscript 2 -- I'm not even sure what version of Flash to be honest. &nbsp;It's been a long time. &nbsp;Anyway, we want to update these, so Flex 3 seems like a natural given our purposes and environment. &nbsp;Without even really adding AS3 or lots of features, the SWF that gets produced is like 450KB. &nbsp;All I did was literally change background color, add a canvas, and then popped in a few form widgets. &nbsp;I didn't even link them to anything. &nbsp;In the old Flash files, the max size of any SWF is 80KB -- and that's with a lot of AS and some small bitmaps. &nbsp;Am I missing something here or is Flex really that bloated? &nbsp;Is there a way to remove unneeded libraries or modules or something to get the file size down?

On a project we had a bunch of old interactive forms made with Flash and Actionscript 2 -- I'm not even sure what version of Flash to be honest.  It's been a long time.  Anyway, we want to update these, so Flex 3 seems like a natural given our purposes and environment.  Without even really adding AS3 or lots of features, the SWF that gets produced is like 450KB.  All I did was literally change background color, add a canvas, and then popped in a few form widgets.  I didn't even link them to anything.  In the old Flash files, the max size of any SWF is 80KB -- and that's with a lot of AS and some small bitmaps.  Am I missing something here or is Flex really that bloated?  Is there a way to remove unneeded libraries or modules or something to get the file size down?

Are Flex files (swf) really this large, or am I doing something wrong?

Adobe Flash (formerly Macromedia Flash) is a cross-platform multimedia and software platform used to embed animations, video, and interactive applications into web pages and desktop and mobile applications and games. Flash displays text, vector and raster graphics to provide animations, video games and applications. It allows streaming of audio and video, and can capture mouse, keyboard, microphone and camera input. The ActionScript programming language allows creation of interactive animations, video games, web applications, desktop applications and mobile applications.

Apache Flex is a highly productive, open source application framework for building and maintaining expressive web applications that deploy consistently on all major browsers, desktops and devices (including smartphones, tablets and television). It provides a modern, standards-based language and programming model that supports common design patterns suitable for developers from many backgrounds. Flex applications can be deployed to the Adobe Player in the browser, Adobe AIR on desktop and mobile devices or to native Android, iOS, Windows or Mac applications.
