What is a B6Z File and How Do I Open It?

A B6Z file is an archive that contains one or more files compressed with B6Z compression.  This compression uses a higher compression ratio than typical algorithms and makes use of a sophisticated compression technique that is now used by other compressors including 7-Zip.  B6Z files may be extracted using a variety of programs, with the most popular being B6Zip.

The B6Z compressor can also be used to create multi-volume, or spanned, archives which are archives that are composed of several compressed files that can be individually downloaded and then recombined.  These files typically have the file extensions B6Z.0 to B6Z.999.

Archiving file formats use a compression algorithm in order to make files smaller. This is done through reducing the file entropy to the lowest point possible. Some files can be compressed to extremely small sizes while other files cannot be compressed much at all because they already have maximum entropy. An example of this is a jpeg image file which already uses a form of compression. Attempting to compress further will not make the image file much smaller. Even though some files cannot be compressed any more than they already are, compression tools are still good for combining multiple files and directory structures into a single archive file. The best way to accomplish this is to use the B6Zip app.

NOTE: The name B6Z stands for the developers who created the compression algorithm.

Our goal is to help you understand the B6Z file suffix and how to open them.  The B6Zip program on this site has been researched for 100% accuracy and verified to work with this particular file extension.  We only publish information about file formats that we have tested and validated.
