ActionScript 2.0 :: Target A Subdirectory With "EXEC"?

Where JPGS2.app is an applescript which resides DIRECTLY inside the fscommand folder the following WORKS:

Code:
on (release) {
butt1.onPress = function(){
fscommand("exec", "openJPGS2.app");
}
}

Where JPGS2.app is an applescript which resided inside the folder "scripts_apl" inside the fscommand folder the following DOES NOT WORK:

Code:
butt1.onPress = function(){
fscommand("exec", ":scripts_apl:openJPGS2.app");
}

The same is true if just for kicks I put ":fscommand" in front of the path. Can I assumer therefore, that the EXEC commond does not allow for nested folders even inside the "fscommand" folder even though Macromedia documentation says otherwise? I know that was an older reference. It is really important that I get a sub folder. I have some 40 applescripts and PC scripts that I will need to run, and I would really prefer them to be tucked nicely away in a folder.
