What is a .ZZ file?
The .ZZ file extension represents a Zzip Compressed Archive. This means it is a type of file that has been made smaller using a program called Zzip. Zzip can be used on computers that run Windows or Unix operating systems. When files are compressed into a .ZZ file, they use a special method to shrink the file size called the Burrows-Wheeler Transform method. This method is good at making files smaller without losing any information. The .ZZ files also have a way to check if the file is still okay after being compressed, and they can even recognize and specially compress multimedia files like pictures and videos.
To open a .ZZ file, you can use the Zzip program. This is the same program that was used to compress the files, so it knows exactly how to open and decompress them.
Another interesting point is about Pigz, which stands for Parallel Implementation of GZip. Pigz is a tool that makes files smaller, similar to how Zzip works, but it usually creates .GZ files. However, Pigz can also compress files in a way that they end up with a .ZZ extension, just like Zzip. This happens when Pigz uses a different method called zlib compression. Sometimes, files compressed with zlib might also have a .ZL extension instead of .ZZ.
So, if you have a .ZZ file, you can open it using Zzip. If you're using Pigz and you set it to use zlib compression, you might also end up creating .ZZ files, which can be opened in the same way.
