how to open exe files that locate in several subfolders with flash projector (mx) ??

Please apoligize my poor english ^^"

I'm using flash mx with fscommand like this...

on (release) {
  fscommand ("exec", "filename.exe");
}

and I put my exe file in the folder name "fscommand", it works with the file in the first level of that folder. But the problem is I have to separate the exe files in subfolders beneath the "fscommand" folder. Because each of exe files has its own group of coding links (I cannot change them as they were created by other people, and I cannot put them together too).

So I build subfolders A,B,C and D in the "fscommand" folder. Each of them contains exe file, now it's like this C://mainfolder/fscommand/A/aa.exe

I tried to change the code into this...

on (release) {
  fscommand ("exec", "A/aa.exe");
}

But it doesn't work.. T_T

Repeat again: I have to link all exe files in separate folder with one flash projector.. How can I do that? Please tell me exact code and what I have to do.. I am not good in coding at all.

thank you in advance :>

ps.. can I use flash 5 to do it? but I want it to be the last option as I have created all the story in flash mx and I don't want to redo it again in flash 5.
