If anyone has done this or has any ideas I'd appreciate any tips.

The set up: Using Flash 5; Internal training piece runs off CD without any internet connection.

Flash File is set up for multiple users to use. For new users, a text file is to be written to hard drive with user info stored as variables. For returning users, an existing text file on their hard drive is accessed to get user information. Text file will be dynamically named based on their employee ID#.

Problem: I need to set up some sort of error check in Flash so that when user logs in, Flash must check to see if the text file already exists(hence it's a returning user and read in info) or no file exists (hence a new user) and so one must be written.

I haven't figured out how to test/error check and see if the file is non-existent or not which will determine which screen to send the user to next.

If anyone has any ideas I'd really appreciate it. Thanks!!
