What is a TAR.BZ2 file?

A TAR.BZ2 file is a TAR archive compressed using the Bzip2 algorithm, which employs the Burrows-Wheeler transform (BWT), Move-to-Front (MTF) transform, and Huffman coding. It offers higher compression ratios than the Gzip (DEFLATE) algorithm but requires significantly more CPU resources for compression and decompression. This format is widely used in Linux distributions for packaging source code and software binaries where bandwidth conservation is prioritized over processing speed.

How to open a TAR.BZ2 file

Linux and macOS systems support this format natively via the terminal using tar -xjf or tar -xvjf. For Windows users, native support is absent, necessitating third-party software such as 7-Zip, WinRAR, or PeaZip. The format allows for streaming decompression, meaning the entire archive does not need to be read before extraction begins.

What is a RAR file?

RAR (Roshal Archive) is a proprietary archive file format developed by Eugene Roshal that supports data compression, error recovery, and file spanning. It utilizes a variation of the LZSS algorithm with a sliding window size of up to 4 MB (in RAR4) or 1 GB (in RAR5), combined with Huffman coding. Key technical features include support for AES-256 encryption, BLAKE2sp hash algorithms for file integrity, and specialized recovery records that allow for the reconstruction of damaged data. The format structure supports solid archiving, where multiple files are treated as a single continuous data stream to improve compression ratios.

How to open a RAR file

Due to the proprietary nature of the RAR licensing, creating RAR files requires licensed software (WinRAR), though extraction is supported by various free tools. Windows users typically use WinRAR or 7-Zip to extract contents. macOS users can utilize The Unarchiver or Keka. On Linux, the non-free unrar package or the open-source 7z (p7zip-full) package provides extraction capabilities via the command line.
