BZ File - opening and understanding

Did your computer fail to open a BZ file? We explain what they are used for and recommend software that we know can open or otherwise handle your .BZ files.

What is a BZ file?

A .BZ file is a BZIP compressed archive file. Files with the .bz file extension are compressed files that have been created by the Bzip file compression software. Bzip can be used to take large files and compress them into a smaller size for easier storage and distribution. The Bzip compression utility is usually found on Unix systems. It combines Run-Length Encoding and the Burrows-Wheeler compression algorithm to significantly reduce the size of a file.

Unlike many file compression utilities, Bzip cannot archive files. This means that only one file can be contained within each .bz file. If a user wants to compress multiple files into a single file archive, the Bzip application must be used along with another utility that is used for file archiving purposes, such as tar.

How to open BZ files

You will need a program compatible with the specific file you are trying to open, as different programs may use files with file extension BZ for different purposes.
