A .ZZ file most often represents a compressed container produced by Zzip or by tools that save raw zlib data.

Historically, the extension became known through Zzip, a compression utility by Damien Debin that runs on both Windows and Unix variants. In that role, a .ZZ file typically holds one or more files that Zzip has compressed using a Burrows–Wheeler–style algorithm, with integrity checks and optimizations for multimedia data. Over time, developers also began using .ZZ as the standard extension for pure zlib streams, which is why tools such as pigz produce .ZZ files whenever the zlib mode (-z or --zlib) is selected. As a result, any given .ZZ file may originate from Zzip or from a zlib-oriented tool, but underneath it still relies on compatible deflate compression concepts. You can usually decompress .ZZ archives using native tools like Zzip or pigz and other zlib-capable programs, but a general-purpose viewer such as FileViewPro simplifies the process by recognizing the extension, identifying whether it is Zzip or zlib data, and presenting the contents through a familiar interface.
A compressed file is compact file packages that reduce the size of the information they hold while keeping it organized and easy to handle. Fundamentally, they operate by looking for repeating patterns and unnecessary duplication so the same information can be written in a shorter form. Because of this, the same drive can hold more information and uploads and downloads finish sooner. Whether it is one spreadsheet or a full collection of mixed files and subfolders, everything can be bundled into a single compressed package, all wrapped into one smaller file than the originals. Because of this versatility, compressed formats appear everywhere, from software downloads and backups to email attachments, game resources, and long-term data archives.
The story of compressed files tracks the progress of data compression research and the rise of everyday desktop computing. During the 1970s–1980s, pioneers like Abraham Lempel and Jacob Ziv developed famous schemes like LZ77 and LZ78, demonstrating that redundancy could be removed without permanently losing information. These ideas eventually led to widely used methods like LZW and DEFLATE, which power many popular compression formats today. Later, in the PC era, programmers including Phil Katz turned compression into something practical for home users through utilities like PKZIP, which popularized the ZIP format and established a simple way to bundle and shrink files on early systems. Since then, many alternative archive types have appeared, each offering its own balance of speed, compression strength, and security features, yet all of them still revolve around the same core principle of compact packaging.
From a technical perspective, compression methods fall broadly into two families: lossless and lossy. Lossless approaches keep every single bit of the original, which is critical when you are dealing with applications, spreadsheets, code, or records. Formats such as ZIP, 7z, and many archive-style containers use lossless techniques to ensure that files can be restored exactly as they were. Lossy compression, by contrast, deliberately discards information that is considered less important, especially in media like audio, video, and certain images. Even when the formats look different on the surface, all compression is still about capturing structure and similarity so files occupy fewer bytes. Beyond just smaller size, archives also act as containers that protect folder structures and metadata in one place.

With the growth of high-speed networks and powerful devices, compressed files have found increasingly sophisticated roles. One major use case is software delivery: installers and app bundles are often compressed so users can get them faster and then expand them locally. Large content libraries are typically stored in compressed archives so that they occupy less disk space and can be patched or replaced without touching the rest of the installation. In system administration and DevOps, compressed archives are indispensable for log rotation, backups, and automated deployment workflows. Distributed systems and cloud platforms continuously compress data behind the scenes, helping keep performance high and bills under control.
Another important dimension of compressed files is their role in archiving, long-term storage, and security. Because they reduce volume, compressed archives allow organizations and individuals to keep years of documents, images, and logs in a manageable footprint. A number of archive types support built-in checksums and recovery records that help detect errors and, in some cases, repair damaged data. Some formats also support encryption and password protection, allowing sensitive documents to be stored in a compressed file that is both smaller and shielded from unauthorized access. Thanks to these features, compressed archives are now routinely used to safeguard business data, personal information, and intellectual property.
For everyday computer users, compressed files also simplify workflows and collaboration. Rather than attaching every file one by one, you can pack them into one archive and send just that, cutting down on clutter and transmission time. Because the layout is kept inside the archive, everyone sees the same structure after extraction. In many cases, applications and support tools automatically generate compressed files when exporting projects, collecting log bundles, or preparing backups. As a result, knowing how to deal with compressed files is now as fundamental as understanding how to copy and paste or move files between folders.
Because so many different compression formats exist, each with its own structure and sometimes its own features, users often need a straightforward way to open and work with them without worrying about which tool created the file. Instead of guessing which program to use, you can rely on FileViewPro to identify and open the archive for you. By centralizing the process into one application, FileViewPro makes it easier to browse archive contents, preview files, and choose exactly which items to restore. Whether you are a casual user, a power user, or somewhere in between, tools like FileViewPro take the complexity out of dealing with compressed files so you can focus on the content rather than the format.
Looking ahead, compressed files will continue to adapt as storage devices, networks, and user expectations evolve. Ongoing research aims to squeeze more out of data while still keeping compression and decompression fast enough for real-time applications. Despite all the innovation, the core goal has not changed; it is still about making big things smaller and more manageable. From personal use to professional environments, compressed archives quietly support tasks that would otherwise be slow, awkward, or expensive. In practice, this means you can enjoy the speed and efficiency of compressed files while letting FileViewPro handle the details in the background.
