How to fix CRC error when unzipping an archive in WinRAR

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

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

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

Configure WinRAR to be able to unzip files with CRC error

By default, the WinRAR application does not allow you to unzip files that have errors or errors, it is before this that the so-called CRC error arises. However, you can change this setting in order to allow WinRAR to unpack 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 said 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 problem document, 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 above settings, you will be able to properly uncompress the file. Keep in mind that many times you will not be able to run or open the document, but many other 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 usually 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 step would be to download the file again (if it was a downloaded file). The truth is that, in most circumstances, data corruption occurs due to an incomplete download, so 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 most likely arose when the document was compressed.

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