How to fix CRC error when unzipping an archive in WinRAR

WinRAR is an excellent data compression and decompression program, with it actions such as putting or removing passwords in a compressed file are possible to protect its content and also others how to solve the CRC error when decompressing a file in WinRAR , which is exactly what that we will talk about in the next tutorial.

What is CRC?

When we refer to CRC we speak directly of the so-called “Cyclic redundancy check”, which comes from “Cyclic redundancy check” . CRC refers to a code designed to detect errors in computer files.

This type of technology is used in computing at a general level, but it is usually known for its integration in file compression and decompression programs, such as WinRAR, which is an excellent program to extract RAR files on your PC or Android device. , being one of the most popular applications for this purpose.

How to fix CRC error when unzipping an archive in WinRAR

Unfortunately, in many cases the cyclic redundancy check indicates that certain information in a compressed file is corrupted or corrupted.

Even so, it is possible to access the rest of the content, so it will be necessary to make a configuration that allows us to decompress and access the information from a document with this problem; Furthermore, it is advisable to take care of the security of our equipment, for this reason we must know if a RAR file contains a virus before downloading it .

Configure WinRAR to be able to decompress files with the CRC error

By default, the WinRAR application does not allow decompressing files that have errors or errors, which is why the so-called CRC error arises. However, you can change this setting in order to allow WinRAR to unzip those files with errors. In addition, it should be noted that on many occasions these files work perfectly.

Read the guide that we present below to properly decompress those files that present the so-called CRC error and thus access this information:

  1. The first thing you should do is open the RAR file that has problems. Then run the document so that it opens with the WinRAR application.
  2. Once you successfully open the document with problems, go to the “Extract to” section.
  3. The WinRAR extraction and configuration screen will be displayed; This is where you must configure as follows: locate the “Miscellaneous” tab and the “Keep damaged files” option You must activate this option and click on “Save options”. Now, click on the “Close” button, do not press “OK” .

If you make the previous configurations, you will be able to properly unzip the file. Keep in mind that many times you will not be able to execute or open the document, but many times you will be able to access the information, so the previous configuration could be useful for you in most cases .

Other solutions to the CRC error

Unfortunately, the so-called CRC error often means that certain files cannot be read properly, which in other words means that the information is corrupted or damaged . It is in this circumstance, that is, when nothing else can be done that it is necessary to take certain measures into account.

The first measure would be to download the file again (in case it was a downloaded file). The truth is that, in most circumstances, data corruption occurs due to an incomplete download , before this the primary solution would be to access the download site again and download the file again.

In relation to the previous point, if you have the same CRC error again, you should contact the person who sent you the file, since the problem may have arisen at the time of compressing the document.

On the other hand, you should also consider other programs and applications for ZIP archives , as a software change may help you to fix this problem if you still have it after all of the above.
