What is a tbz file?
A tbz file is a shorthand extension for .tar.bz2, representing a POSIX tarball compressed with the Bzip2 algorithm. Developed by Julian Seward, Bzip2 utilizes the Burrows-Wheeler Transform (BWT) followed by Move-to-Front (MTF) transforms and Huffman coding. This stack allows for significantly tighter compression than the traditional gzip (DEFLATE) method at the cost of higher CPU usage during compression and decompression. It is widely used in BSD operating systems for packaging ports and system files.
How to open a tbz file
Linux and macOS environments natively support tbz extraction via the command line using tar -jxf file.tbz, where the -j flag invokes the bzip2 decompressor. For Windows users, 7-Zip, WinZip, and WinRAR all possess the necessary libraries to decode the BWT blocks and extract the internal tar archive without requiring command-line interaction.

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.
