GZ File - opening and understanding

Did your computer fail to open a GZ file? We explain what they are used for and recommend software that we know can open or otherwise handle your .GZ files.

What is a GZ file?

A .GZ file is a GZip Compressed Data file. The .gz file extension is given to Gnu Zipped file archives. The Gnu Project developed this file format for use on Unix operating systems to compress large files. For example, if you have a file that you would like to send via email, the GZ file format would allow you to compress it into a much smaller file.

GZ archive files are compressed using the GNU (Gzip) compression algorithm. The .gz files can contain one file only. If you want to include multiple files in a GZ file, you first need to "combine" them using an archive tool like TAR. That will create a .tar.gz or .tgz file.

You can open GZ files on both Mac and Windows operating systems. You can also open them on computers that are running Linux.
