Directory browse dialog?

[talig]

Hi everyone,
My plugin writes text files of computed information, and I want to enable the user to choose where he wants those file to be saved.
A webDialog won't do here (as far as I can tell) because <input type="file"...> requires to choose a file, and I need a directory, and I don't want to use <input type="text"...> due to obvious usability reasons.
Ideas?
Thanks,
