Adam Buyer, project leader at B1:
“The new version of our archiver is a great step towards making it more convenient for users. Nevertheless, our team is focused on improving its features even further to meet the highest expectations. For the next version we are focusing on improving b1 compression algorithm. Our developers have been working on it for quite a while, and we expect very good results in the 0.5 version, with remarkable speed to compression ratio.

Since last release we received a few dozens of grateful letters from our users from all over the world. It’s really inspiring and we’re going to keep doing our best to stay on that way. Also we received very valuable feedbacks and suggestions, so we corrected our road-map according to requests of our users. We are glad to stay in touch with you, so please do not hesitate to contact B1 support should you have any question or if you just want to tell us what you think of B1 Free Archiver.”
