ما هو؟
GZ (Gzip) هي صيغة ضغط ملفات وبرنامج حاسوبي تم إنشاؤهما بواسطة Jean-loup Gailly و Mark Adler عام 1992. يستخدم خوارزمية ضغط DEFLATE التي تجمع بين ضغط البيانات بدون فقدان LZ77 وترميز Huffman. تم إنشاء Gzip كبديل مجاني لبرنامج Unix compress الذي استخدم خوارزمية مشمولة براءات اختراع. امتداد .gz يشير إلى ملف واحد مضغوط باستخدام gzip، أما لأرشيفات المجلدات فعادة ما يتم دمج gzip مع tar لإنشاء ملفات .tar.gz أو .tgz.
Gzip هي أداة الضغط القياسية على أنظمة Linux و Unix وهي مدمجة فعلياً في كل توزيعة Linux. يتم استخدامها على نطاق واسع لضغط ملفات السجلات وملفات الإعدادات وحزم البرامج. تستخدم خوادم الويب ضغط gzip لتقليل حجم استجابات HTML و CSS و JavaScript و JSON قبل إرسالها إلى المتصفحات، مما يقلل محتوى النصوص عادة بنسبة 60 إلى 80%. تتضمن صيغة gzip رأس بسيط يحتوي على اسم الملف ووقت التعديل، متبوعاً بتدفق البيانات المضغوطة.
المواصفات التقنية
الإيجابيات والسلبيات
Advantages
The universal compression standard on Unix and Linux - available on every system without installation.
DEFLATE compression is significantly faster than bzip2 or xz, making gzip suitable for frequent compression tasks.
Built-in web server feature for compressing HTTP responses, reducing page load times by 60 to 80% for text content.
Supports single-pass streaming compression, making it ideal for compressing data in pipes and over networks.
Disadvantages
Gzip compresses only one file at a time. To compress a directory, you must first create a tar archive.
DEFLATE provides good compression but bzip2 and xz consistently produce smaller files at the cost of slower processing.
Does not support splitting compressed output across multiple files.
Unlike ZIP or 7Z, a.gz file does not contain a directory listing - just compressed data for a single file.

How to open a GZ file
GZ files, created using the Gzip compression algorithm, are commonly used for compressing single files or streams. Software for handling GZ files can be categorized into professional tools, free/open-source options, browser-based applications, and built-in utilities.
Professional tools are ideal for users needing advanced features and support, while free/open-source options cater to budget-conscious users or developers. Browser-based applications offer convenience for quick tasks, whereas built-in utilities provide basic functionality without additional installations.
When choosing software for GZ files, important factors include feature fidelity, whether the software is intended for editing or simply viewing, and the cost model. Users should consider platform compatibility, as some tools are limited to specific operating systems. Additionally, understanding when to convert GZ files to other formats can influence the choice of software, especially if the user needs to extract or manipulate the contents frequently.
