Summary:- When a person has a large-sized file and he is unable to send it due to the size limit then he compresses that file into one Zip file. It reduces the size of the file and you can share it with anyone. But sometimes an improper compression of the file leads to ZIP files corruption issues and you cannot open and access the ZIP file. Therefore, here you can see various methods to repair and open a corrupted ZIP file on your computer. Once you fix the corruption issues of the file, you can easily expand the file and open all the contents present in it. But before you learn how to fix a corrupted ZIP file, you must go through the meaning and reasons for ZIP file corruption.
Zip File is one of the most popular files among all the other file formats that we use as storage space and also to send large files over the internet through emails. It is created using WinZip utility and can compress the files up to 50 – 90 %, depending on the file type. Zip files are easily transferable through emails over the internet in less time and also possess the benefit of instant downloads.
When you try to extract data from a zip file, the extraction process gets terminated halfway and shows an error message like “The Compressed (zipped) Folder is invalid or corrupted”. Then another question comes how to repair corrupted zip files?
So let’s start by moving the story forward as follows –
Zip files can get corrupted due to many reasons and one of them is the oversizing of zip files. If the size limit is more than 2GB then often it gets corrupted because WinZip allows creating of zip files of a maximum of 2 GB size.
There are several other reasons for the corruption of zip files such as
Corruption of zip files occurs because WinZip cannot verify stored data and thus cannot extract it. Corruption generally makes the file header corrupt and thus the archive becomes unreadable. If the ZIP file is damaged, CRC values of the original files of an archive don’t match the extracted ones, the standard tools won’t extract them.
There are two ways to open a corrupt ZIP file. Either you can try the manual method that needs a lot of technical expertise or directly move on to the automated tool for hassle-free recovery.
The WinZip Command Line Support Add-On contains functions that attempt to repair Zip files (.zip or .zipx). The proper versions are listed and can be downloaded from the Alternative Download Links web page. If you are using a version earlier than WinZip 11.2, you can download the proper add-on version from the Legacy Download Links page. Access to a Command Prompt window will also be necessary.
Note:- Substitute the actual drive letter and folder where WinZip is installed if different than above and also use the real Zip file name in the place of zipfile.zip. The double quotes in the example above are necessary due to the space between “Program” and “Files”.
“C:\Program Files\WinZip\wzzip” -yfs zipfile.zip
A new Zip file will be created by WZZIP and a FIXED suffix in the file name also. The original Zip file will not be modified. Only the data will be used which are available in the original Zip files.
The FIXED Zip file is structurally sound but the data may still be corrupt. WZZIP does not fix the zipped data itself. If the zipped data has a CRC error or corruption, then the resulting fixed Zip file will still be corrupt.
If you still didn’t get a proper solution and continue to have difficulty please try the Zip Repair tool from Sysinfotools.
