Gzip stands for GNU zip. The utility was writtel to be distributed freely with full source code by Jeal-loup Gailly and Mark Adler. Using gzip offers a high level of file compression and freedom from software patents and restrictions. Files created by gzip will have a ".gz" file extension and can be extracted on Windows using the command-line version of gzip created for Windows.

Skill level:


  1. 1

    Save the GZip file located in the Resources section below.

  2. 2

    Open the downloaded zip file and extract it to "C:\Windows\System32." This step will ensure it is in your system's path.

  3. 3

    Click "Start" and then type "CMD" in the Search bar. Windows 2003 and earlier users must click "Run" first.

  4. 4

    Navigate to the directory containing your GZip file using the CD command. For example, if it is in "C:\Users\John\Files" you would type: cd C:\Users\John\Files.

  5. 5

    Extract the file with the command "gzip -d <filename>." For example: gzip -d johnspictures.gz

  6. 6

    Open your extracted files. They will be located in the same directory as the zipped file.
