Did you have a look at swf kit pro 3??
In swfkit pro 3,if you choose to give a encryption password to a swf file, then when the exe run in windows, you can't find the swf content from memory.
This feature is very usefull if you don't want your swf file to be saved by others.
How can we achieve this purpose with FPC?
With the newest version of FPC trial, the content of the swf file that being played can be found in the memory. So you can use tools such as Flash Vampire to save it.
PS:if you want me to give you a example of swfkit pro3 out file and the flash vampire,I can send you a email. And let you to have a try.
