Too Much Memory Usage

Hi!!
If you look at the pic

If u look at the bottom left, there is my task manager.it says memory usage is 221,612K (216MB). isn’t that too much? whenever I make a flash movie with some pics in it. the memory usage goes up like crazy. I was making another movie other day and memory usage was going up to 200+… if there any way to avoid that? because not all computers have the same amount of memory, some computers will just crash when I run this on those computers.

Please tell me what can I do to fix this problem. also what should be memory usage for a normal flas movie, I know it depends on what type of movie it is, but just gimme a rough idea.

Thanks
