How to Open a CPGZ File

By Alexander Poirier

The CPGZ file format is a file format used with the Mac OS X Unix-based operating system. The file format itself is actually a combination of two formats, it is a CPIO file compressed with the GZ compression. If you wish to open a CPGZ file, you can do so easily, using the default decompression application that comes with every Mac computer.

Step 1

Press and hold the "Ctrl" key and click on the CPGZ file you want to open.

Step 2

Move your mouse cursor over the "Open With" option in the context menu that appears.

Step 3

Select the "Apple Archive Utility" option from the Open With menu. The Apple Archive Utility will now open the CPGZ file.
