Multiple save and load text (theory)

I understand flash does not allow to save text to file, but i have been using zinc 3.0 and can save and load a single text file within flash.

  1. Can someone please run me through what the theory would be to have multiple input text fields that save to 1 text file and then is able to load the text from those text fields back into the same place? In theory or if someone knows how to do this in zinc it would be great.

  2. Is it possible to automatically load and save text to files using something similar to flush() with shared objects?

  3. Is it possible to have a username and password so multiple people can save and load there own answers? Perhaps having this password on the first frame as i have multiple frames with stops and multiple textboxes.
