B1 Free Archiver Review !

B1 has versions for Windows, Mac, Linux and Android and calls itself a friendly and simple archiver. The program can only archive in ZIP or its own open source B1 format which uses LZMA compression. Nearly 30 formats can be extracted including 7z and ZIPX. Pay attention to the installer as it pre-ticks an option to send statistical data to B1, download the standalone setup file to get the full installer and not the online downloader. The website also has a useful online unarchiver which can extract several different formats without needing software.
