Hi Irina,
I'm sorry, but I cannot convert these. I need either a .tab file in UTF-8 format or the three stardict files .dic (or .dict), .ifo and .idx. I'm on linux, so I don't know what the pc program is supposed to do. Maybe you can take a look at
http://www.babylon.com/free-dictionaries/. I can convert the bgl files found there.
Kind regards,
Ruud
