*** Frequently Asked Questions

• Where can I get the password?
  If you were asked to enter password that does NOT mean you need password for B1 Archiver.
  It means that your archive is password-protected, which means that people how created that archive encrypted it with a secret password. Please check this article for most common ways to find password - http://b1.org/help/Where-can-I-get-the-password-to-the-archive.jsp

If you 100% sure that your archive is regular and not protected, but you are still asked for the pass - please send it to [email protected] for investigation, it might be an issue with the software.
