What is a GZ file extension?

GZ files are archives that have been compressed with the Gnu Zip (gzip) software. They are generally used on UNIX operating systems. The .gz files can only contain one file, to add more files you must first create a TAR archive. GZ files can be opened on Mac, Windows and Linux.

WinRAR is the third most installed software after Google Chrome & Acrobat Reader, making it the World’s most popular compression file utility!
