Did your computer fail to open a BZ2 file? We explain what they are used for and recommend software that we know can open or otherwise handle your .BZ2 files.

What is a BZ2 file?

A .BZ2 file is a BZIP2 Compressed Archive file. Files with the .bz2 file extension are compressed files that have been created by the Bzip2 file compression software. Bzip2 can be used to take large files and compress them into a smaller size for easier storage and distribution. The Bzip2 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, Bzip2 cannot archive files. This means that only one file can be contained within each .bz2 file. If a user wants to compress multiple files into a single file archive, the Bzip2 application must be used along with another utility that is used for file archiving purposes, such as BitZipper.
