About GZ Files

Gzip compresses a single file. It can't hold several files by itself, so folders are first bundled with TAR and then compressed, producing .tar.gz files. Gzip is everywhere on Linux and servers: log files are rotated to .gz, software is shipped as .tar.gz, and web servers use the same compression to send pages faster. Most archive tools open .gz files.

How to Open a GZ File

Mac & Linux
Double-click it, or run gunzip file.gz (or tar -xzf file.tar.gz) in a terminal.
Windows
Windows 11 opens .gz in File Explorer. Otherwise use 7-Zip, or tar -xzf in Command Prompt.

GZ File Questions

What's inside a .tar.gz file?

A TAR archive compressed with gzip. Extract it once to get the files and folders.

Can gzip compress a folder?

Not on its own. Bundle the folder with tar first, or use tar -czf, which does both.
