Excellent plugin! Puntuado con 5 de 5 estrellas

Now, when you helped me, I can say with a clear conscience, that your plugin is perfect! Thank you! Sorry for the jump to conclusions.
I'm leaving my old comment and your response for the others.

[Lack of polish symbols makes that plugin a trush. All folders which contain polish letters can't be opened...]

Polish symbols do work. You might have to change the encoding you are working with to download the file. Go to Account Manager->Advanced->Server Encoding and perhaps try West European->Western (ISO-8859-1) or whatever region the server might be located in (e.g. Chinese servers tend to use East Asian->Chinese Simplified (GB18030))
