B1 Free Archiver is a simple, neat and handy file archiver that lets you both create new archives and open existing ones. Though it’s powerful and reliable, it’s provided completely for free. The program is, in fact, an open source archiver whose source code can be downloaded and modified without any problem.

B1 Free Archiver is very easy-to-use. Its interface is neat, intuitive and straightforward. Even its options are well explained and simple to understand. It’s a self-explanatory program that can be used with ease even by beginners.

Ease of use is not the only advantage of this tool. It’s a powerful archiver that supports various archiving formats and compression algorithms. It can handle ZIP, RAR, 7Z, ARJ, and TAR archives but it also allows creating and managing archives using its own proprietary format, B1.

Furthermore, it can be used to create password-protected archive files with the 256-bit AES encryption. Archives can also be split, using pre-defined criteria, the processing speed of extracting and creating archives is pretty fast, and the possibility of selecting among different compression levels is also provided.

The only downside of this tool is that when it comes to creating new archives, only the ZIP and B1 formats are supported. Other than that, there’s nothing else to criticize about it. It’s a really nice and handy tool.

Cutting long story short, B1 Free Archiver is a great choice whenever you need a powerful yet easy-to-use and free file archiving utility.
