A tar.gz file contains several compressed files to save storage space, as well as bandwidth during the downloading process. The .tar file acts as a portable container for other files and is sometimes called a tarball. The .gz part of the extension, stands for gzip, a commonly-used compression utility.
how to open gzip compressed archive file
Note: Some graphical interfaces include a tool for managing tar.gz files without the command-line. Simply right-click the item you want to compress, mouseover compress, and choose tar.gz. You can also right-click a tar.gz file, mouseover extract, and select an option to unpack the archive.
gz/gzip is a file format and a software application used for file compression and decompression. The program was created by Jean-Loup Gailly and Mark Adler as a free software replacement for the compress program used in early Unix systems, and intended for use by the GNU Project (the "g" is from "GNU").
gz/gzip is based on the DEFLATE algorithm, which is a combination of LZ77 and Huffman coding. DEFLATE was intended as a replacement for LZW and other patent-encumbered data compression algorithms which, at the time, limited the usability of compress and other popular archivers.
Although its file format also allows for multiple such streams to be concatenated (zipped files are simply decompressed concatenated as if they were originally one file), gz/gzip is normally used to compress just single files. Compressed archives are typically created by assembling collections of files into a single tar archive, and then compressing that archive with gz/gzip. The final .tar.gz or .tgz file is usually called a tarball.
gz/gzip is not to be confused with the ZIP archive format, which also uses DEFLATE. The ZIP format can hold collections of files without an external archiver, but is less compact than compressed tarballs holding the same data, because it compresses files individually and cannot take advantage of redundancy between files (solid compression).
To open/extract gz/gzip file on Windows, you can use 7-Zip, Easy 7-Zip, or PeaZip. 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.
To open/extract gz/gzip file on Mac, you can use B1 Free Archiver. 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 gz/gzip.
It's easy on Linux. Just use gunzip command. gunzip can currently decompress files created by gzip, zip, compress, compress -H or pack. The detection of the input format is automatic. When using the first two formats, gunzip checks a 32 bit CRC.
Where .zip files consist of many individually compressed files, .tar files are compressed as a single package, leaving its files uncompressed. In other words, .zip files are a collection of compressed files, while .tar files are a compressed collection of files.
You can create your own compressed .tar files using compression utilities such as gzip. Gzip is one of the most popular and available options, especially since it comes built in to most Linux distributions and macOS.
If you want to keep the original file after compression, there are two options. The first is the -k option, and the other uses the -c option to output the compressed file to a different file, preserving the original.
With the command prompt open, use the appropriate commands to change the current working directory (cd) to the location of the .tar.gz file you want to unzip. Alternatively, you can also specify a source and destination file path when using the tar utility.
While every tar.gz file is a .tar archive, not every .gz is a .tar file. The .gz extension represents the gzip compression format, which can be applied to almost any file format to compress data and save space.
Though both .zip and .tar.gz archive and compress files, they do so in different ways. Where .zip archives and compresses individual files, .tar only archives individual files, leaving a separate compression format such as .gz (gzip) to compress all of them as a single file/archive. In other words, .zip is a collection of compressed files, while .tar.gz is a compressed collection of files.
Yes. Since .tar.gz compresses multiple files all at once, it can take advantage of similarities between individual files to save on space. Generally speaking, a collection of files archived and compressed as a .tar.gz will be more space-efficient (i.e., smaller) than the same collection compressed as a .zip.
That concludes the complete information GZ file and how one can extract and open GZ file easily on your Linux system. We have included four different methods to extract GZ files without having any errors. These methods are tried and tested on various Linux machines, so you can use these methods on your Linux system without facing issues.
Japanese versions of Windows encode ZIP archives with Shift-JIS. By default, these archives will suffer from mojibake filenames when extracted.To extract properly, use unzip in the command-line using the shift-jis option.
Options: -c : Creates Archive -x : Extract the archive -f : creates archive with given filename -t : displays or lists files in archived file -u : archives and adds to an existing archive file -v : Displays Verbose Information -A : Concatenates the archive files -z : zip, tells tar command that creates tar file using gzip -j : filter archive tar file using tbzip -W : Verify a archive file -r : update or add file or directory in already existed .tar file
Examples: 1. Creating an uncompressed tar Archive using option -cvf : This command creates a tar file called file.tar which is the Archive of all .c files in current directory.
5. Creating compressed tar archive file in Linux using option -j : This command compresses and creates archive file less than the size of the gzip. Both compress and decompress takes more time then gzip.
gzip is a file format and a software application used for file compression and decompression. The program was created by Jean-loup Gailly and Mark Adler as a free software replacement for the compress program used in early Unix systems, and intended for use by GNU (from where the "g" of gzip is derived). Version 0.1 was first publicly released on 31 October 1992, and version 1.0 followed in February 1993.
gzip is based on the DEFLATE algorithm, which is a combination of LZ77 and Huffman coding. DEFLATE was intended as a replacement for LZW and other patent-encumbered data compression algorithms which, at the time, limited the usability of compress and other popular archivers.
Although its file format also allows for multiple such streams to be concatenated (gzipped files are simply decompressed concatenated as if they were originally one file),[5] gzip is normally used to compress just single files.[6] Compressed archives are typically created by assembling collections of files into a single tar archive (also called tarball),[7] and then compressing that archive with gzip. The final compressed file usually has the extension .tar.gz or .tgz.
gzip is not to be confused with the ZIP archive format, which also uses DEFLATE. The ZIP format can hold collections of files without an external archiver, but is less compact than compressed tarballs holding the same data, because it compresses files individually and cannot take advantage of redundancy between files (solid compression).
The tar utility included in most Linux distributions can extract .tar.gz files by passing the z option, e.g., tar -zxf file.tar.gz, where -z instructs decompression, -x means extraction, and -f specifies the name of the compressed archive file to extract from. Optionally, -v (verbose) lists files as they are being extracted.[12]
zlib is an abstraction of the DEFLATE algorithm in library form which includes support both for the gzip file format and a lightweight data stream format in its API. The zlib stream format, DEFLATE, and the gzip file format were standardized respectively as RFC 1950, RFC 1951, and RFC 1952.
Since the late 1990s, bzip2, a file compression utility based on a block-sorting algorithm, has gained some popularity as a gzip replacement. It produces considerably smaller files (especially for source code and other structured text), but at the cost of memory and processing time (up to a factor of 4).[14]
In addition to these convenience functions, gzip module also has GzipFile class which defines the compress() and decompress() methods. The constructor of this class takes file, mode and compressionlevel arguments exactly with same meaning as above.
Tar archives combine multiple files and/or directories together into a single file. Tar archives are not necessarily compressed but they can be. Permissions are preserved and it supports many compression formats.
