Another useful troubleshooting feature built into Flash is the Size Report. (See Figure 5.14.) The Size Report is a text file that lists the size (in bytes) of every frame and every element in your Flash file. The report is broken up into different sections:
Movie Report. This tells you how much information has to download for each individual frame.
Page. This gives the size of all items on the stage that are not symbols. Text, grouped items, and drawn graphics are listed here.
Symbol. This lists the name and the size of each symbol, as well as the size of any text used in the symbol, for your movie.
Bitmap. This lists the imported bitmapped images. This section is particularly useful because it shows the uncompressed size, along with the compressed size for each element. Thus, you can get a quick visual check of how compressed each element is.
Sound. This lists all the sounds, their sizes, and the compression ratios.
Font. This lists all the fonts that you use in your movie. Notice that Flash imports only the characters actually used in your movie.
