File Extension GZ

File type: Gnuzip (GNU Zip) Compressed Archive

About the GZ file type:

If Windows cannot find the appropriate program associated with .GZ files, then your registry may have errors. Check your Windows registry for errors (includes file association errors).

The .GZ file extension identifies Gzip compressed archives developed as a free application as part of the GNU development project. GZ will most probably contain compressed data which can be uncompressed using a range of popular file archiving applications including WinZip, WinRAR and Allume Systems Stuffit Expander, to name only a few. These same applications can be used for creating .GZ files.

Additional Information:
GIMP image files also use the .GZ file extension.
