WinRAR is basically a file format utilized for transferring bulky files and folders over the network by compressing them with the help of numerous compression algorithms or techniques. In other words, compressing multiple files into a single file called WinRAR archive.
CRC error is one of the scenarios responsible for WinRAR file damage. It occurs when there is some problem in unzipping RAR files. CRC error means that the disc has failed to perform Cyclic Redundancy Check. It takes place because of intentional damage, dust, scratches etc. The main logic behind it is that there is a rotating checksum for each and every byte, when that checksum doesn’t match up because of any reason then this CRC message will pop up and it will restrict the unzipping process of RAR files. It consists of an analysis to make sure that files when copying / moving on the other side also appear properly. If the WinRAR file is corrupt because of any reason, the process of checking will stop at that particular time and you need to re-download the file or you have to take the help of reliable WinRAR repair tool in order to know how to fix WinRAR successfully.
