We are new to Flash development. I have a Flash site with a user registration page. When users have completed a number of details and when clicked 'register', I want to exit cleanly and save an encrypted id and last session date in a specific user folder.
Can Flash write to client side file system, say c:\user\$user\appdata\roaming\$myapplication\registered.txt
If not, what design options or other technologies do I need ?
Any great ideas will be appreciated
Writing to a user's machine via a web site is a security no-no. If you could write to a user's machine via a web site you would be a dangerous site to visit.
If you want this interaction to take place on the web then you will probably need to create a database for your users where you store information. Look into using PHP with a MySQL database to manage storing user information.
If this is supposed to be more in the way of cookie information that your site will retrieve when visitor returns then look into using Flash's SharedObject class.
