Hi, yes it needs to specify a file, not a folder, eg.
Code:
rapidSpell.setParameterValue('default', 'UserDictionaryFile', 'C:\\path\\to\\user\\folder\\userdic.txt');
Also, I'd encourage you to use ~/ type notation for the path, because you don't want the server path (C:\\path...) in your HTML really, security.
Best
Jim
