Edit: You download the lists from the website.
Dude, there is no question about "What I should to do if I want to use free list offline". Of course, I have to download this list and import it into my Byki application via "View list" tab at the top. Actually, the question is "What is the way to download the free list from Byki website onto my computer. Where is the download link to particular wordlist, not the 'Byki' application itself?"
Let me explain the problem I stucked. I want to download some word list. To do this I go to the byki/listcentral.html. Then I chose, for example, I choose the "Chinese" language because I want to learn some more Chinese phrases. It takes me to /category/Chinese/a. Then I choose some list, for example, this one: /lists/Chinese/CC-lesson-1.html. So, what do I see? The online version of Byki so I now can to train online. But I want to download list onto my computer and use it via my Byki application, right? Well, I suppose, I should push one of this two pretty buttons under the title "Download this list". The one button is "Windows", the other is "Mac OSX". When I tap "Windows" it takes me to /download_sd.plex?reply_w_2.plex?li=39370461000000175174. What I get is a Byki loader that starts to download a new Byki application copy for me. Not the list itself. So, there is a question: Where can I obtain a direct link to the list file with .b4u extension? What is a step-by-step procedure to do it?
Well, I've done reverse engineering and finally found the way to get direct link to any list.
When I tap "Windows" it takes me to /download_sd.plex?reply_w_2.plex?li=39370461000000175174
You have to copy that link and change it this way:
This is a direct link to .b4u file which you can import into your Byki manually
