Key Takeaways

• A GZ file is a compressed archive created using GNU Zip (gzip).

• Windows 11 doesn’t natively support GZ files, but you can easily open them using free tools like 7-Zip, WinRAR, or PeaZip.

• You can also extract GZ files via the Command Prompt or PowerShell for a built-in solution.

• Opening and extracting a GZ file is quick and doesn’t require advanced technical skills.

What Is a GZ File in Windows 11?

A GZ file (with the .gz extension) is a compressed file created by the GNU zip (gzip) compression algorithm. Think of it like a digital vacuum sealer: it takes large files and “squeezes” them into a smaller size, making them easier to store or transfer.

On Windows 11, you’ll most often encounter .gz files when:

• Downloading software source code from GitHub.

• Receiving log files from Linux servers.

• Handling large text or data files compressed for faster sharing.

Why Do You Need to Open GZ Files in Windows 11?

You might ask, “Why can’t I just double-click the file?” The truth is, Windows Explorer doesn’t natively support GZ extraction. Without the right tool, double-clicking often results in a confusing prompt or error.

By opening and extracting .gz files, you can:

• Access the original data or documents inside.

• Work with cross-platform files from Linux or macOS.

• Save disk space by keeping files compressed until needed.

How to Open GZ File in Windows 11: Step-by-Step Methods

Now let’s dive into the step-by-step instructions for different ways to handle GZ files.

---

Method 1: Open GZ Files Using 7-Zip (Free and Popular)

7-Zip is one of the most popular free tools for handling compressed files, including .gz.

Steps:

1. Go to the 7-Zip official website.

2. Download the latest version (choose 32-bit or 64-bit depending on your system).

3. Install 7-Zip on your PC.

4. Right-click the .gz file.

5. Hover over 7-Zip > Extract Here or Extract to folder_name.

6. Your GZ file will be extracted, revealing the contents inside.

💡 Pro Tip: Most .gz files contain a single file, often with a .tar extension. If you see a .tar file after extraction, simply repeat the process to unpack it.

Method 2: Open GZ Files with WinRAR

WinRAR is another widely used compression tool, though it’s technically paid software (with an indefinite free trial).

Steps:

1. Download and install WinRAR.

2. Right-click the .gz file.

3. Select Extract Here or Extract to <folder>.

4. WinRAR will decompress the file, and you can access the original content.

Method 3: Open GZ Files with PeaZip

PeaZip is a free, open-source alternative with a clean interface.

Steps:

1. Download and install PeaZip.

2. Launch PeaZip and open the .gz file.

3. Click Extract and choose a destination folder.

4. Access the decompressed files.

Method 4: Open GZ Files Using Windows Command Prompt

If you prefer not to install third-party tools, you can use built-in Windows utilities.

Steps with Command Prompt:

1. Press Windows + S and type cmd, then select Run as administrator.

2. Install Windows Subsystem for Linux (WSL) if you haven’t already (since gzip is a Linux-native utility).

   • Run: wsl --install

3. Once WSL is installed, open your .gz file with the command:

   gzip -d filename.gz


4. The file will be extracted in the same folder.

---

Method 5: Open GZ Files Using PowerShell

PowerShell can also handle GZ extraction with a simple script.

Steps with PowerShell:

1. Right-click Start and select Windows PowerShell (Admin).

2. Navigate to the folder with your .gz file using:

   cd "C:\path\to\folder"


3. Run the extraction command:

   Expand-Archive -Path "file.gz" -DestinationPath "C:\output\folder"


4. Your GZ file will be extracted to the specified folder.
