What is a .CPGZ file?
The file extension .CPGZ represents a Compressed CPIO Archive. This type of file is a compressed archive that uses two methods to store data: the Copy In, Copy Out (CPIO) format and gzip compression. The CPIO format is a method for archiving files, while gzip is a compression technique that reduces the file size. This combination is similar to a .TGZ file, which uses a .TAR container for archiving and gzip for compression. However, .CPGZ files specifically use the CPIO format instead of TAR.
.CPGZ files are commonly used on Unix-based operating systems, such as Linux and Mac OS X. These files allow for efficient data storage and transfer because they compress the data, making the files smaller.
To open a .CPGZ file, you can use several programs: 1. **ditto** - A command-line utility available in macOS that can extract and compress files. 2. **Apple Archive Utility** - This is a built-in utility in macOS that can handle various compressed file formats, including .CPGZ. 3. **The Unarchiver** - A versatile program that can open many different types of compressed files. It is available for macOS. 4. **ditto** (mentioned again as it can both compress and decompress these files).
These tools help you access the contents of .CPGZ files by decompressing them, allowing you to use the files stored inside.
