Answer 1

Had same problem. Used CONCAT to manually add extension. It does not appear in the dialog box when saving but DOES save as a text file with a .txt extension when viewed in Windows Explorer. Doesn't seem to work but actually does!

var final_filename:String = filename.concat(".txt");

//Create text to save from text field var newDataFile:TextField = new TextField(); newDataFile.text=myTextField.text; //create file reference to save file var file:FileReference = new FileReference(); file.save(newDataFile.text, final_filename);
