What is a .BZ2 file extension?

These are files that have been created using bzip2 compression software, used most commonly on Unix and Linux systems. The .BZ2 format can only compress single files. You should compile all files into an archive first, then use bzip2 to compress the archive. This is often done using the TAR utility.

WinRAR is the World’s third most installed software after Google Chrome & Acrobat Reader, making it the World’s most popular compression file utility!
