What is an XZ file?
The XZ format is a single-file compression container utilizing the LZMA2 algorithm, designed as a modern replacement for the POSIX gzip and bzip2 formats. It features a streamable structure with index integrity checks via CRC32 or SHA-256 and supports dictionary sizes up to 4 GB. The format is maintained by the Tukaani Project and is the default compression method for software package distribution in many Linux ecosystems (e.g., Fedora, Arch).
How to open an XZ file
XZ files are natively supported on most modern Linux distributions via the xz-utils package. On Windows and macOS, users must install third-party archiving tools; 7-Zip (Windows) and The Unarchiver (macOS) provide robust support for decoding the LZMA2 streams used in XZ files.

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.
