B1 Archiver Information

B1 Free Archiver is a file compressor and decompressor, which is available on all platforms and is completely free.

Its simple interface is very similar to the famous WinRAR, with options to create or decompress archives at the top, and a window to browse your hard drive at the bottom.

Its compression format is B1, but can also unzip other well-known formats such as ZIP, RAR or 7Z.

Of course, when creating archives, B1 Free Archiver also allows them to be broken down into separate parts, with the added convenience of some presets such as the maximum size allowed by Gmail.

This is, without doubt, an excellent free option to compress and decompress files quickly and easily.
