Overview
What is a ZZ file? File archive compressed with Zzip, a compression tool for Windows and Unix; uses a compression algorithm based primarily on the Burrows-Wheeler Transform method; supports file integrity tests and built-in multimedia detection and compression.
More Information Pigz (which stands for Parallel Implementation of GZip) is a compression utility that typically compresses files using GZip compression. These compressed files are saved as .GZ files. However, pigz users can also compress files using zlib compression. In that case, the compressed files are saved as ZZ files. NOTE: Zlib compressed files may also be saved with the .ZL extension.
