Are you running out of space on your Windows PC? The best thing you can do to free up some space is to compress big files through zipping. There are plenty of third-party tools that can come in handy in this situation.

However, if you prefer to use Command Prompt or Windows PowerShell over anything else, there are commands you can use in these utilities to zip or unzip files. So, let's check out how to zip or unzip files using Command Prompt and Windows PowerShell.

How to Zip Files Using Command Prompt

You can zip files through Command Prompt using the tar command. It's a command line tool that helps you to extract files and create archives. However, this command only works in Windows 10 or later.

Here's how to zip files using Command Prompt:

  1. Open the Start Menu by pressing the Win key.
  2. In the search bar, type Command Prompt and Run as administrator from the right pane.
  3. In the console, type the following command and press Enter. Replace 'Place' with the location of the file.
            cd Place
        
    Place of the file
  4. Type dir and press Enter. It'll show the files inside the selected folder.

  5. To zip all the files inside the selected folder, type the following command and press Enter. Replace 'Compressed' with the name you want to give your folder where the zip file will be stored. Also, replace 'FileExt' with the extension of the file you're zipping.
            tar -a -c -f Compressed.zip *.FileExt
        
    Tar command in CMD
  6. To zip a single file, execute the following command. Again, replace 'Compressed' with the name you want to give your folder where the zip file will be stored, 'FileExt' with your file's extension, and 'FileName' with the name of the file you want to zip.
            tar -a -c -f Compressed.zip FileName.FileExt

How to Zip Files Using Windows PowerShell

There are several viable ways to create zip files on Windows. One of these is through Windows PowerShell. However, the tar command doesn't work in Windows PowerShell; we'll use another command to get the work done.

Here's how to zip files using Windows PowerShell:

  1. Open the Start Menu, type Windows PowerShell, and choose Run as administrator from the right pane.
  2. In the console, type the following command and press Enter. Ensure to replace file destination and target location with the location of the file and the place where you want the file to be zipped, respectively. Also, replace file name with the name of the file you want to zip and destination name with the destination folder name.
            Compress-Archive -LiteralPath 'file destination\file name' -DestinationPath 'target location\destination name'

If you want to zip multiple files, execute the following command. Replace file destination and file destination 1 with the location of the first and second files, respectively. And replace file name and file name 2 with the first and second file names.

        Compress-Archive -LiteralPath 'file destination\file name', 'file destination 1\file name 2 -DestinationPath 'target location\destination name'
Zipping 2 files at once

How to Unzip Files Using Command Prompt

There may be situations where you want to unzip files on your Windows computer. Fortunately, you can do that as well using Command Prompt. Here's how:

  1. Launch Command Prompt with admin privileges.
  2. Use the cd command to head toward the zip file's location.
  3. Type the following command and press Enter. Replace 'Name' with the name of the zip file.
            tar -xf Name.zip
        
    Unzipping file in CMD

You've successfully unzipped the file.

How to Unzip Files Using Windows PowerShell

Windows PowerShell lets you quickly unzip files on your computer. Here's how to do that:

  1. Open Windows PowerShell with admin rights.
  2. Type the following command and press Enter. Make sure to replace <file destination> and <target location> with the location of the zip file and the place where you want the file to be unzipped, respectively.
            Expand-Archive -LiteralPath <file destination> -DestinationPath <target location>
