Have you encountered a problem with a GZ file? Don’t you know which program opens a file with this extension? You will find all the information you need about working with a GZ file here. In the further part of this page we have added a list of programs that should open your GZ file. It is enough you choose a proper application for your operating system, download and install it.


GZ is the file extension for gzip compressed files. Gzip stands for GNU zip, which is a free compression method based on the Deflate algorithm. GZ files should not be confused with zip archives. Gzip is part of almost every standard installation of Linux systems, but has no meaning on Windows and Mac OSX.

Gzip archives can in principle contain only a single file, but this can be circumvented by first combining the files with tar into a tarball and then packing them with gzip. These are usually recognized by the double ending .Tar.Gz or simply .Tgz.

GZ archives can be unpacked by just about any packer, be it Linux, Windows or Mac. This also applies to tgz files.

How to open a GZ file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the GZ file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a GZ file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support GZ files. At this point we are looking for disk space where the application was installed in and we can link it with a GZ file. Since then, our operating system will use the selected program to support all GZ files.

Other issues

Despite the described problem with GZ there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the GZ file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the GZ file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
