Downloading and running files

Question

Hi there,
I am wondering if I can develop a ac code to download file
from my secure server and run the file into the local PC using
Adobe AIR application with Flex. I have notice there is
FileReference.download() method; however, this method displays the
box to ask the user where to save the file. What i need to do is to
download the file in specific location i would decide the location.
Is there any way i can do this with Actionscript 3.0.
thanks for your fast reply.

Due to security restrictions, you cannot download a complete
file to a directory of your choice. The
FileReference.download()/upload() does not allow the programmer to
access the nativePath information, even if it is an AIR
Application. It's pretty much all black box.
The option you have is to download the file into binary data,
then save the file from the data. This is a very tricky thing to
do, but it is along the same idea as dragging and dropping a
picture; you're able to save data from flex onto the local
filesystem.
