Can AS3 recognize operating system & call appropriate file (wmv vs. mov)?

Question

Hi, I'm using Flash CS3 to create a graphical interface with
multiple buttons--each of which opens a different linked file. The
interface and linked files will all be included on a memory stick
given out to people. The code below works perfectly for calling up
a .wmv file (from a folder in the root drive called "linked_files")
when a button is clicked. But my question is this:
Is there a way for AS3 to recognize whether a computer is
running Windows (in which case it would open the .wmv) or Mac OS
(in which case it would open a .mov instead)?
I need to do the same thing with a couple of .exe files.
Obviously Mac won't read them, in which case I need an appropriate
alternative to open.

Hi dreamrhts,
Take a look at the os property of the capabilities class:

You can't use navigateToUrl to execute an exe file.
Your only option for this would be through fscommand (only
works in standalone projector!). Depending one your needs
third-party projector tools maybe necessary.
Dont know anything about mac executables though.
Good luck !
