Being proficient in managing zip files not only makes file storage efficient, but also enhances your sharing and backup processes. This guide is designed to walk you through the essential steps to zip and unzip files using PowerShell on both Windows 10 and 11, with actionable instructions to boost your productivity.

How to Zip Files Using PowerShell

To compress files and folders into a zip file using PowerShell, follow these steps:

  1. Open the Start Menu.

  2. Search for PowerShell, right-click the icon, and select Run as administrator.

  3. Execute the following command to compress the desired files or folders:

    Compress-Archive -Path C:\SOURCE\PATH\TO\YOUR\FILES\* -CompressionLevel Optimal -DestinationPath C:\DESTINATION\PATH\ZIPPEDFILE.zip

    Make sure to replace the paths with your actual directories. The wildcard * allows the command to compress all contents in the specified folder.

After executing these steps, you will have a zip file containing all selected files and folders.

Include Additional Files in a Zip Archive

To update your existing zip file with new files or folders, follow this process:

  1. Open the Start Menu.

  2. Search for PowerShell, right-click the icon, and select Run as administrator.

  3. Run the following command to include additional files in the zip archive:

    Compress-Archive -Path C:\SOURCE\PATH\TO\YOUR\FILES -Update -DestinationPath C:\DESTINATION\PATH\ZIPPEDFILE.zip

After completing this process, your zip archive will now contain the newly specified files.

Adjust Zip Compression Ratio

To modify the compression level of a zip file in PowerShell, proceed with the following steps:

  1. Open the Start Menu.

  2. Search for PowerShell, right-click the icon, and select Run as administrator.

  3. Use the command below to compress files with a specified compression level:

    Compress-Archive -Path C:\SOURCE\PATH\TO\YOUR\FILES\* -CompressionLevel Fastest -DestinationPath C:\DESTINATION\PATH\ZIPPEDFILE.zip

Set the CompressionLevel parameter to control how quickly you want the files to compress:

  • Fastest: Quick compression, resulting in a larger zip size.
  • NoCompression: No compression, zip file size equals uncompressed files.
  • Optimal: Best space-saving, though requires more time.

Your zip file will be created based on the selected compression setting.

How to Unzip Files Using PowerShell

    Expand-Archive -Path C:\SOURCE\PATH\TO\YOUR\ZIPFILE\ZIPPED.zip -DestinationPath C:\DESTINATION\PATH\UNZIP

Executing these steps will extract all contents from your specified zip file to the target location.

Additional Tips
