exec a executable file

[alvin3343]

Hi,
I exec a file useing this expression:

fscommand("exec","files\\update.exe");
(of course I pack swf to swfkit app)

1.
but update.exe can't load his assets which is in "files" forder.
How can I make update.exe located in its original forder?

2.
and how to pass param to update.exe?
can I write code like this ?
fscommand("exec","files\\update.exe -q -e");

thank you very much
