![]() The seven types of packets are as follow ( Wikipedia) Packed code (bit sequence)Ī single byte encoded using an adaptive binary range coder.Ī typical LZ77 sequence describing sequence length and distance. To do what people do with WinRAR and 7-Zip, people usually use tar along with one of the data compression tools mentioned above to created compressed archives (.tar.gz. gzip (.gz), bzip2 (.bz2) and xz(.xz) are all data compression tools and they don’t archive files. The length and distance of each packet is implicitly or explicitly encoded. tar is an archiving program and it doesn’t compress files. I hope you're using SharpCompress and finding it useful. XZ has known holes explained here: ( Use Tar/LZip for LZMA compression instead. Each packet describes either a single byte or an LZ77 sequence. 7Zip does not support streamable formats. lzipis a free, command-linetool for the compression of data it employs the LempelZivMarkov chain algorithm(LZMA) with a user interface that is familiar to users of usual Unix compression tools, such as gzipand bzip2. The LZMA compressed format consists of a compressed stream of bits that is encoded using adaptive binary range coder. LZ are based on the LZMA (Lempel-Ziv-Markov chain) algorithm and include a 32-bit CRC checksum and ident bytes for checking the integrity of the file. ![]() In general, xz achieves higher compression ratios, but needs a lot more memory and time. To extract a tar.xz file, invoke the tar command with the -extract (-x) option and specify the archive file name after the -f option: tar -xf. gzip and xz uses two different algorithms, and therefore they perform differently, both in terms of what level of compression they achieve and in terms of the amount of resources they consume while compressing or decompressing. Extracting tar.xz File The tar utility is pre-installed by default on all Linux distributions and macOS. LZ files have media type application/lzip and support higher compression rations than BZ2. This article explains how to use the tar command to extract (or unzip).

Tools to compress/decompress xz and gzip files are also available on Windows systems, but are more commonly seen and used on UNIX systems. We also have this paradigm for video files for example: avi/mkv/mov/mp4/ogv are containers, and xvid/x264/theora are compression algorithms. Long answer: think of xz as a container for the compression data generated by the lzma2 algorithm. It supports concatenation to compress support files. Short answer: xz is a format that (currently) only uses the lzma2 compression algorithm. lz extension is a compressed archive file created with Lzip, which is a free command-line tool for compression.
