Opening BZ2 files

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

What is a BZ2 file?

Files with the .bz2 file extension are compressed files that have been created by the Bzip 2 file compression software. Bzip 2 can be used to take large files and compress them into a smaller size for easier storage and distribution. The Bzip 2 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 2 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 Bzip 2 application must be used along with another utility that is used for file archiving purposes, such as BitZipper.

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
