TAR (Tape ARchive) is both a file format (in the form of a type of archive bitstream) and the name of a program used to handle such files. The format was created in the early days of Unix and standardized by POSIX.1-1988 and later POSIX.1-2001.
Initially developed to write data to sequential I/O devices for tape backup purposes, tar is now commonly used to collect many files into one larger file for distribution or archiving, while preserving file system information such as user and group permissions, dates, and directory structures.
A tar archive consists of a series of file objects. https://bestzup234.weebly.com/we-the-revolution-1-3-0.html. Each file object includes any file data, and is preceded by a 512-byte header record. The file data is written unaltered except that its length is rounded up to a multiple of 512 bytes. The original tar implementation did not care about the padding and left the buffer unaltered, but most modern tar implementations fill the extra space with zeros. The end of an archive is marked by at least two consecutive zero-filled records. (The origin of tar's record size appears to be the 512-byte disk sectors used in the Version 7 Unix file system.) The final block of an archive is padded out to full length with zeros.

The tar format continues to be used extensively in Unix, Linux and OS X. Linux versions use features prominently in various software distributions, with most software source code made available in .tar.gz (gzip compressed tar archives). The tar format is a basis of some types of containment and distribution.
tar archive files usually have the extension .tar, as in somefile.tar. The pun, tarball, is used to refer to a tar file.
A tar archive file contains uncompressed byte streams of the files which it contains. To achieve archive compression, a variety of compression programs are available, such as gzip, bzip2, xz, lzip, lzma, or compress, which compress the entire tar archive. Typically, the compressed form of the archive receives a filename by appending the format-specific compressor suffix to the archive file name. For example, a tar archive archive.tar, is named archive.tar.gz, when it is compressed by gzip.
| Short | Long | Compression |
| .tgz | .tar.gz | gzip |
| .tbz, .tbz2, .tb2 | .tar.bz2 | bzip2 |
| .taz, .tz | .tar.Z | compress |
| .tlz | .tar.lz, .tar.lzma | lzma |
| .txz | .tar.xz | xz |
To open/extract TAR file on Windows, you can use 7-Zip, Easy 7-Zip, PeaZip, and so on. I recommend Easy 7-Zip. The Easy 7-Zip is an easy-to-use version of 7-Zip. The open source freeware keeps all features of 7-Zip and adds a few useful features that makes the software more user-friendly.
Easy 7-Zip works on Windows 10/8.1/8/7/Vista/2008/2003/XP/2000 (both 32-bit and 64-bit compatible).

To open/extract TAR file on Mac, you can use Mac OS built-in utility Archive Utility, or third-part freeware. For example: GUI Tar, The Unarchiver, Keka, or B1 Free Archiver. B1 Free Archiver is recommended. B1 Free Archiver is a free software for creating archive folder and extracting archive file. B1 Archiver works on all platforms - Windows, Linux, Mac and Android. The freeware supports most popular formats including TAR.
B1 Free Archiver is compatible with:
You need to use command tar. The tar is the GNU version of tar archiving utility.
To extract/unpack a tar file, type:
| $ tar -xvf file.tar |
To extract/unpack a .tar.gz (gzip) file, type:
| $ tar -xzvf file.tar.gz |
To extract/unpack a .tar.bz2 (bzip2) file, type: Sftp cyberduck mac.
| $ tar -xjvf file.tar.bz2 |
xz is a lossless data compression program and file format which incorporates the LZMA compression algorithm. xz compresses single files as input, and does not bundle multiple files into a single archive. It is therefore common to compress a file that is itself an archive, such as those created by the tar or cpio Unix programs.
xz has gained notability for compressing packages in the GNU coreutils project, Debian family of systems deb (file format), openSUSE, Fedora, Arch Linux, Slackware, FreeBSD, Gentoo, GNOME, and TeX Live, as well as being an option to compress a compiled Linux kernel. In December 2013, the Linux kernel maintainers kernel.org announced that they would use xz instead of bzip2 as their compression tool from 2014 on.
txz is short for tar.xz. tar.xz is an archive created with tar and xz utilities; contains one or more files first archived using tar and then compressed using xz compression; compressed using a high compression ratio. Beginning with Slackware 13, TXZ files are used to distribute Slackware Linux packages. They can be opened using various Slackware package management tools, including pkgtool and installpkg. Due to the high compression ratio, TXZ files are typically smaller in size than .TGZ files.
Compared to a few other popular stream compression formats, the .xz format provides a couple of advanced features. At the same time, it has been kept simple enough to be usable in many embedded systems. Here is a summary of the features:
Easy 7-Zip opens/extracts xz/txz/tar.xz file easily on Windows. The Easy 7-Zip was developed based on 7-Zip. 7-Zip is a famous open source file archiver. The Easy 7-Zip is an easy-to-use version of 7-Zip. The open source freeware keeps all features of 7-Zip and adds a few useful features that makes the software more user-friendly.

You need to install xz-utils. XZ Utils is free general-purpose data compression software with high compression ratio. XZ Utils were written for POSIX-like systems, but also work on some not-so-POSIX systems. XZ Utils are the successor to LZMA Utils. The core of the XZ Utils compression code is based on LZMA SDK, but it has been modified quite a lot to be suitable for XZ Utils. The primary compression algorithm is currently LZMA2, which is used inside the .xz container format. With typical files, XZ Utils create 30% smaller output than gzip and 15% smaller output than bzip2.
XZ Utils consist of several components:
Install xz-utils on CentOS and Fedora
| # yum install xz-utils |
Install xz-utils on Debian and Ubuntu
| $ sudo apt-get install xz-utils |
Extract xz file
| $ unxz file.xz |
Or
| $ xz -d file.xz |
Compress a file with xz compression
| $ xz file |
Extract txz/tar.xz file
| $ tar xvJf file.txz $ tar xvJf file.tar.xz |
Compress a directory with tar and xz compression
| $ tar cvJf file.txz /dir_name $ tar cvJf file.tar.xz /dir_name |
