Select Control > Test Movie to test the Flash document. If the Components load too
quickly, select View > Simulate Download from the SWF file. Flash simulates downloading
the Flash document at a lower speed, which allows you to see the progress bar component
animate as the class files download.

Using ASO files
During compilation, Flash sometimes creates files with .aso extensions in the /aso
subdirectory of the default global classpath directory (see
classpath" on page 240). The .aso extension stands for ActionScript object (ASO). For each
ActionScript 2.0 file that is implicitly or explicitly imported and successfully compiled, Flash
generates an ASO file. The file contains the bytecode that's produced from the associated
ActionScript (AS) file. Therefore, these files contain the compiled form (the bytecode) of a
class file.
Flash needs to regenerate an ASO file only when the following scenarios occur:
The corresponding AS file has been modified.
ActionScript files that contain definitions imported or used by the corresponding
ActionScript file have been modified.
ActionScript files included by the corresponding ActionScript file have been modified.
The compiler creates ASO files for caching purposes. You might notice that your first
compilation is slower than subsequent compilations. This is because only the AS files that
have changed are recompiled into ASO files. For unchanged AS files, the compiler reads the
already-compiled bytecode directly out of the ASO file instead of recompiling the AS file.
The ASO file format is an intermediate format developed for internal use only. It is not a
documented file format and is not intended to be redistributed.
If you experience problems in which Flash appears to be compiling older versions of a file you
have edited, delete the ASO files and then recompile. If you plan to delete ASO files, delete
them when Flash is not performing other operations, such as checking syntax or exporting
SWFs.
