How Do I Use 7-Zip on Windows 11?

Downloading and Installing 7-Zip

Open your web browser.
Go to the official 7-Zip website: Navigate to www.7-zip.org.
Choose the correct version: Select the appropriate download link for your Windows 11 system (usually the 64-bit version).
Download the installer.
Run the installer: Double-click the downloaded .exe file.
Follow the on-screen instructions: Accept the license agreement and choose an installation directory (the default is usually fine).
Click “Install” to complete the installation.

Compressing Files with 7-Zip

Locate the files or folders you want to compress.
Right-click on the selected files or folders.
Hover over “7-Zip” in the context menu.
Choose “Add to archive…” This will open the 7-Zip archive creation window.
Set your desired archive settings:

Archive: Specify the name and location for the new archive file.
Archive format: Choose the desired archive format (e.g., 7z, ZIP, TAR). The 7z format generally offers the best compression.
Compression level: Select the compression level (e.g., Store, Fastest, Fast, Normal, Maximum, Ultra). Higher compression levels result in smaller files but take longer to compress.
Encryption: If you want to encrypt the archive, enter and confirm a password.

Click “OK” to start the compression process.

Extracting Files with 7-Zip

Locate the archive file you want to extract.
Right-click on the archive file.
Hover over “7-Zip” in the context menu.
Choose one of the extraction options:

“Extract Here”: Extracts the files to the current directory.
“Extract to \[folder name]\”: Creates a new folder with the archive’s name and extracts the files into it.
“Extract…”: Opens a dialog box where you can specify the extraction directory.

If you chose “Extract…”, select the destination folder and click “OK”.
If the archive is password-protected, you will be prompted to enter the password.

Creating a Self-Extracting Archive

Follow steps 1-4 of “Compressing Files with 7-Zip” above.
In the 7-Zip archive creation window, select “7z” as the Archive format.
Check the box labelled “Create SFX archive”.
Set any other desired archive settings (compression level, encryption, etc.).
Click “OK” to create the self-extracting archive.

Encrypting Files with 7-Zip

In the 7-Zip archive creation window, enter a password in the “Encryption” section.
Re-enter the password in the “Reenter password” field to confirm.
Choose an encryption method (AES-256 is recommended).
Click “OK” to create the encrypted archive.

Tips for Using 7-Zip

Use the 7z format for the best compression ratio. The 7z format generally provides better compression than ZIP, especially for large files.
Experiment with different compression levels. Higher compression levels result in smaller files but take longer to compress. Choose a compression level that balances file size and compression time.
Encrypt sensitive data. If you are compressing sensitive data, be sure to encrypt the archive with a strong password.
Create self-extracting archives for easy distribution. Self-extracting archives can be opened on computers that do not have 7-Zip installed.
Integrate 7-Zip with the Windows Explorer context menu. This makes it easy to compress and extract files directly from Windows Explorer.
