How do I compress a .zip file in Windows?

If you need to compress a .zip file in Windows, there are several ways you can do this depending on the version of Windows you are using.

Windows 10

On Windows 10, you can use the File Explorer to compress your .zip files. To start, open the File Explorer and locate the folder containing the .zip file. Right click on the .zip file and select “Send to” from the drop-down menu. Next, select “Compressed (zipped) folder” from the submenu. This will create a compressed version of the original .zip folder with a much smaller size. You can move the compressed file to another location or rename it if desired.

Another way to compress a .zip file in Windows 10 is to use the built-in zip command line tool. To do this, open your command prompt by typing cmd and pressing enter. Next, type “zip” followed by a space and the name of your zip file. For example, if your file is called “”, you would type “zip”. This will create a compressed version of the .zip file in the same location as the original.

Windows 7

If you are using Windows 7, you can also use the File Explorer to compress your .zip files by following the same steps outlined for Windows 10. Alternatively, you can use the free 7-Zip utility to compress .zip files. To do this, download and install 7-Zip from their official website. Once installed, open the application and select the “Tools” tab at the top of the window. Then select “Add to archive” from the drop-down menu. Choose the archive type as “zip” and then select the source file (the .zip file you want to compress) and choose the destination file (the name and location you want your compressed file to be stored). Finally, click “OK” and the compressed file will be created.


Compressing a .zip file in Windows can be done using either the File Explorer or compression utilities such as 7-Zip, depending on your version of Windows. Compressing a .zip file will reduce its size significantly, making it easier to transfer via email or online services.
