File archive compressed with Zzip, a compression tool for Windows and Unix. It uses a compression algorithm based on the Burrows-Wheeler Transform method. ZZ files are supported by software applications available for devices running Linux, Windows.
A ZZ file may also be a compressed archive created by pigz. Pigz is a compression utility published by the developers of the zlib compression format. In pigz, ZZ files are created using the -z or –zlib commands.
Zzip software was developed by Damien Debin. On its official website you may find more information about ZZ files or the Zzip software program.
Pigz uses multiple processors and multiple cores when compressing data. It can archive larger files much faster than with gzip. Pigz does what gzip does, but it allocates the work to multiple processors and cores to speed up compression/decompression.
There is no extension defined for raw deflate-compressed data that I know of. The gzip utility can read gzip-wrapped deflate data or single-entry zip files, but not zlib or raw deflate.
Corruption of a ZZ file can also block the ability to operate it. Below is a list of possible problems: Corruption of a ZZ file being opened.
ZZ is the file extension given to files compressed using Zzip compression tool. Zzip produces better compression compared to tools like Winzip 7.0.
We have free online ZZ file apps that allow to view, edit, convert from to ZZ, merge, split and compare the ZZ files without installing anything.
The main program that supports the ZZ format is Zzip. Although it can be found on any operating system, it will only be useful on Linux, Windows.
