Well, i am so sorry bothering you, i didn't notice that they are all free. Would you please tell me if they are free for commercial use or they are just free for test.

Thank you so much for your generosity. I will pick few more and send them to you via pm. When you will have time, please get them for me. And don't bother yourself by scanning files with Virustotal, i will scan them by myself before download.
