Are you having trouble opening a ZIP file on your Windows PC? Possibly, the file is corrupted. The good news is that there are a couple of ways to repair a corrupted ZIP file on Windows and view its content.

Download the ZIP File Again

When you try to open a corrupted ZIP file , Windows will display an error message like “Compressed (zipped) Folders Error: Windows cannot open the folder. The Compressed Folder is invalid.”

In this case, your first step should be to re-download the ZIP file. This can be helpful if the file was corrupted during download due to interruptions like a system crash, BSOD or pausing/resuming the download process multiple times. This time, ensure the download completes without any disruptions.

If you’ve received the ZIP file through email, ask the sender to send the file again. Make sure to request that they create a new ZIP file from scratch with the same files instead of sending the same potentially corrupted file again.

Use WinZip Command-Line Utility to Repair the ZIP File

WinZip is a popular archive extraction tool for Windows . It also has a command-line utility that you can use to repair corrupted files. To begin with, visit the WinZip official website and download its free version.

Once the download is complete, install it like you install any other software on your computer.

    `cd "C:\Users\Username\Desktop"`

Type the following command and hit Enter. Make sure to replace “ABC.zip” with the actual filename of your corrupted ZIP:

    `"C:\Program Files\WinZip\wzzip" -yf ABC.zip`

Press any key from your keyboard to continue.

WinZip will start repairing the ZIP file. Once the repair process is complete, WinZip will create a separate, repaired ZIP file in the same location as the corrupted one.
