Every File Compression System Explained

Compression systems are what make large files smaller, faster to share, and easier to store—but not all formats work the same. In this video, we break down the most common compression systems used across Windows and Linux, including ZIP, RAR, and 7-Zip on Windows, along with Gzip, Bzip2, and tar on Linux.

We’ll explain how each format works, what algorithms they use, and why some are better for speed while others focus on maximum compression. By the end, you’ll understand when to use each tool and what’s actually happening behind the scenes when your files get compressed.
