Flash files are used widely, but when people use it, they always need new demand. People always chase perfect. SWF files optimization is one of the chasing things. Here is the tip for how to optimaiz flash swf files.
General optimization
Please use symbols, animated or otherwise, for every element that appears more than once. You need to use tweened animations when you are creating animation sequences, because these animations occupy less file space than keyframs. Use movie clips instead of graphic symbols for animations sequences. You need to reduce the area of change in each keyframe as possible as you can to make the action happen in as small area as possible. Try your best to avoid animating bitmap elements and use bitmap images as background or static elements.
Colors
You can use Color menu in the Symbol Property inspector to create many instances of a single symbol in different colors. Then you need to use Color Mixer to match the color palette of the document to a browser-specific palette. Use gradients sparingly. You need about 50 bytes for filling an area with gradient color. You can use alpha transparency sparingly because it can slow playback.
Texts and fonts
You need limit the number of fonts and font style. Please use embedded fonts sparingly because they can increase file size. Select only the needed characters instead of including the entire font for Embed Fonts options.
Lines and elements
Do your best to group elements. You can separate elements that minimize the number of separate lines that are used to describe shapes by using layers. Reduce the number of special line types as possible as you can, such as dashed, dotted, ragged. Solid lines require less memory and lines that are created with the Pencil tool need less memory than brush strokes.
