What is a BZ2 file extension?

Files that have the BZ2 extension have been created using the open source compression software bzip2, which is typically used on UNIX or Linux systems. Th BZ2 format is used to compress single files only and is not able to archive a group of files. That means you need to assemble the group of files you want to compress into an archive first, then apply bzip2 compression to that archive file. On UNIX/Linux, this file archiving is commonly done with the TAR utility. If you receive a .bz2 file, you can decompress bz2 with WinZip by following the steps below.
