How to Fix Invalid Zip Files using Command Prompt

Although Zip files are known for their reliability and effective compression technique, they are not free of issues. You will often face errors such as ‘Invalid Zip file’, ‘CRC errors’ etc. and in this article, our focus is on ‘Invalid Zip file’.

To resolve these errors, one effective way is to download or get another copy of the Zip file. This will help you solve the issue in many cases.

However, in cases when you can’t get another copy of the file or if the new copy doesn’t help you fix errors, you will need to repair the file using other methods. Now let us learn what the other methods are and how you can resolve ‘Invalid Zip file error’.

Solution 1: Using Command Prompt

If you’re using WinZip software to handle your Zip files, you should know that there is a Command Line Add-on provided and is available for download here. Once you have the add-ons downloaded, follow the steps below to repair your Zip file.

  1. Click on Windows + R keys to open the Run window
  2. In the Run window, type ‘cmd’ and hit Enter
  3. Type ‘cd <folder name>’ to go to the folder where the corrupt Zip file is located
  4. Then type ‘C:\Program Files\WinZip\wzzip’ –yf <name of the zip file.zip

This command does not work on the actual Zip file itself but only extracts data from your file, so your original data is safe.

Please note that this method is used to repair the structure of the file only. If your file has corrupt data in it or if your file has a CRC error, this method does not work. In that case, you will have to make use of Zip repair tools such as Yodot Zip repair software.
