A file ending in .ZOO is best described as a compressed container file in the Zoo archive format. Zoo was developed in the mid-1980s by Rahul Dhesi and released for Unix-like systems as well as platforms like MS-DOS and AmigaOS.

Internally, .ZOO files use a variant of the Lempel–Ziv–Welch (LZW) compression algorithm to pack data, allowing one or more files and directories to be stored losslessly in a single compact archive. One notable capability of .ZOO archives is that they can store several historical versions of a file, keeping older revisions alongside newer ones for backup and comparison. In modern computing, the Zoo format is mostly obsolete and overshadowed by formats such as ZIP, RAR, and 7z, yet .ZOO files continue to show up in vintage downloads and retro computing archives. Support for opening .ZOO archives survives in various modern archivers, and multi-format viewers like FileViewPro make it easier for users to identify the file type, browse what is inside, and pull out individual files even if they have never installed the classic Zoo utility

Compressed files are compact file packages that reduce the size of the information they hold while keeping it organized and easy to handle. At their core, they work by looking for repeating patterns and unnecessary duplication so the same information can be written in a shorter form. As a result, your storage space stretches further and your transfers are completed with less waiting time. A compressed file can contain a single document, an entire folder tree, or even complex software installations, all wrapped into one smaller file than the originals. That is why almost every workflow, from simple file sharing to professional data handling, relies on compressed files somewhere along the way.

The story of compressed files tracks the progress of data compression research and the rise of everyday desktop computing. In the 1970s and 1980s, researchers such as Abraham Lempel and Jacob Ziv introduced the foundational LZ77 and LZ78 algorithms, 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. In the late 1980s and early 1990s, developers like Phil Katz helped bring file compression to everyday users with tools such as PKZIP, cementing ZIP as a go-to format for compressing and grouping files. Over time, other developers and companies added new formats that focused on higher compression ratios, stronger encryption, or better error recovery, but the basic idea stayed the same: take one or more files, apply an algorithm, and produce a smaller archive that is easier to move and manage.

From a technical perspective, compression methods fall broadly into two families: lossless and lossy. With lossless compression, nothing is permanently thrown away, so it is safe for any information where accuracy matters. 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. Whether it is a generic archive or a specialized media format, the underlying goal remains to squeeze out wasted space while keeping the content useful. In most archive formats, compression is tightly integrated with packaging, so you can both reduce size and preserve a complete directory layout inside a single file.

With the growth of high-speed networks and powerful devices, compressed files have found increasingly sophisticated roles. Software distribution is a prime example, where applications are shipped as compressed packages that download quickly and then unpack into their full structure on the user’s device. Game developers bundle textures, sounds, levels, and configuration files into compressed assets to reduce load times and save storage space while keeping updates manageable. 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.

Compressed files are equally valuable when you are preserving information for the long haul or protecting it from prying eyes. With compression, large historical datasets and personal collections that would otherwise be unwieldy become easy to back up and move. 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.

On the practical side, compressed files remove a lot of friction from sharing and organizing information. A single compressed package keeps related files together, which is often much tidier than sending them individually. Because the layout is kept inside the archive, everyone sees the same structure after extraction. Backup tools frequently use compressed archives so they can capture snapshots of entire folders or systems efficiently. Even users who never think about compression explicitly still benefit from it every time they download, install, or restore something.

With numerous formats in the wild, it is common for users to run into archives they have never seen before and are not sure how to open. This is where an all-in-one viewer such as FileViewPro becomes especially valuable, because it is designed to understand many different compressed formats. By centralizing the process into one application, FileViewPro makes it easier to browse archive contents, preview files, and choose exactly which items to restore. For anyone who regularly downloads software, works with shared projects, or receives large bundles of documents, having a dependable way to open and manage compressed files through FileViewPro turns compression technology into something practical, convenient, and easy to trust.

The role of compressed files is likely to grow even more important as digital content keeps expanding. Ongoing research aims to squeeze more out of data while still keeping compression and decompression fast enough for real-time applications. Even as hardware improves, storage and bandwidth are not infinite, so compression remains an essential tool. Whether you are emailing a handful of photos, archiving years of work, distributing software, or backing up business systems, compressed files continue to do the heavy lifting in the background. In practice, this means you can enjoy the speed and efficiency of compressed files while letting FileViewPro handle the details in the background.
