In webApp. I want to create file in users desktop with some name and I want to write into it How to do this? is it possible using File reference?
Filereference.save() method i tried but it opens dialog box for saving, but i want file to be save in given path without opening dialog box.

From a browser based Flash app; you cannot save a file to the users machine in Flex without user input. FileREference.save() is the correct approach, but as you discovered it opens a dialog box for user input.
Depending what information you need to store; a local Shared Object may work. Adobe has some good documentation on using Shared Objects:
