Download/Save/Write a file on the client's hard disk using flash/flex

Programmer Question

Hi,

I wonder how can I download/save/write a file from my server to a client's computer using flash or flex.

An example of what I'm looking for is
avilable on
http://www.flexdownloads.com

1. Sign up


2. Sign in


3. Click on the ("FREE") button placed on the right of the page. (the
   orange button)


4. Choose any product (won't cost you anything)


5. Press "BUY NOW"

then you'll see a confirmation popup
for the download, then you choose
where do you want to save the file,
and the flash movie saves the file!
