GZ File

GZ file is a kind of compressed files with a filename extension standing for GNU Zip.

Created by Jean-Loup Gailly and Mark Adler., GZ is a software application used for file compression.

The file format GZ 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 archives.

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 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.

GZ archives are often used with tar files. Tar files are archives too, but they don’t enable any compression. Gzip allows you to lower the size of a tar archive and it is recommended to use the combination. So, first of all, you need to create a tar archive of anything you like. As you deal with directories, fisrt create an archive of a directory.


You need to create an archive of wp-content folder. In order to do this, please type:


Wp-content.tar is the resulting filename of a tar archive. Your server will think some time and then content.tar will appear in your folder.


Now you need to gzip it. Please, pay attention to the file size on the screenshot below.


And now the final operation is to gzip the file with the following command:


This will compress your tar archive without any messages too.


Please pay attention to the size: the file is now compressed and ready for download.
