Open CPGZ File

The CPGZ extension is used for compressed type files that combine the Copy In, Copy Out file format with the CPIO extension and the gzip compression of the GZ extension.

Similar to a TGZ archive, which incorporates both a TAR container and GZIP compression.

The CPGZ is used most frequently on Unix-based systems such as Linux and Mac OS X.

The CPGZ files are used on web servers, as it allows you to compress the resources of a web page before they are served to users' browsers so that the web page loads faster and improves in this way in WPO.

The understanding on which this type of CPGZ file is based has become very popular in recent times among different WPO consultants thanks to tools such as Google Page Speed Insights which have given it much importance.

Corrupt ZIP files

The CPGZ files can be created by double clicking on a ZIP file on Mac OS X.

When opening the ZIP file, a new file is created with the same name but with the extension CPGZ.

Then, when decompressing the CPGZ file, this becomes the original ZIP file.

This loop is produced because the ZIP file is corrupt.

It could be corrupt due to an incomplete download or because the original ZIP file was not compressed correctly.

To solve this problem, try re-downloading the ZIP file again.

DITTO command

On Linux and Mac OS X systems, you can create and extract CPGZ files using the DITTO command line program.

DITTO is a powerful tool that has the capacity, not only to copy files from one directory to another, but it also preserves the file hierarchy, extracts content from a ZIP or CPGZ, or compresses the content in the directory that you specified as destination .

In addition, DITTO is suitable for copying directories with many subcarpets.
