What is a TGZ file?

The TGZ file extension represents a Tape Archive (TAR) wrapper compressed using the GNU Gzip utility, combining the POSIX.1-2001 Ustar archival standard with the DEFLATE compression algorithm (RFC 1952). It utilizes LZ77 coding and Huffman entropy encoding to provide high-ratio lossless compression for directory trees while preserving file system metadata such as permissions and timestamps. This composite format is standard in Unix-like environments for software distribution.

How to open a TGZ file

Linux and macOS systems provide native support via the command-line tar utility (using the -z flag). Windows users require third-party archival software to decompress the Gzip layer and untar the contents; 7-Zip and WinRAR are the industry-standard recommendations for handling the dual-layer extraction process on non-Unix platforms.

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.
