Imagine this: You've just downloaded an important file, but instead of the usual .zip or .pdf, you're staring at something called .GZ. What is a GZ file? How do you open it? Is it some kind of secret code from the depths of the internet?
GZ files are super common, especially in the tech world, but they can leave newcomers scratching their heads. But they're actually pretty easy to unzip once you know how to handle them.
In this guide, we'll simplify everything about .GZ files, including their properties and transparent instructions to decompress GZ files on Windows, Mac, Linux, and online platforms. Let's get started!
In this article
Part 1: What is a GZ File
A GZ file is a compressed archive created using the GNU Zip (GZip) compression algorithm. The GZip software functions as a free Unix system replacement for compress, which now serves as a preferred file compression tool due to its effective and efficient operation. A GZ file functions primarily to shrink the original file size so users can efficiently save and transmit it.
File Format and Structure of .GZ File
The GZ file format uses the DEFLATE compression algorithm, which combines LZ77 and Huffman coding to compress data effectively. A typical GZ file contains:
- Header: Includes metadata such as the file name, timestamp, and compression method.
- Compressed Data: The actual data code (compressed to reduce size).
- Footer: Contains a CRC-32 checksum and the original size of the uncompressed data for integrity verification.
Common Uses of GZ Files
GZ files are predominantly used on Unix-based systems like Linux and macOS but can also be found on Windows platforms. They are commonly used for:
- Compressing Single Files: Reducing the size of individual files for storage efficiency.
- Packaging Multiple Files: Users create .tar.GZ or .tGZ archives with both tar and GZip utilities to bundle several files into a unified compressed file package.
- Software Distribution: Compressing software packages and source code for easier distribution and installation.
