What is a CRC error?

CRC or Cyclic Redundancy Check is an error-detection process which helps to determine if the data sent and received is the same. If the check matches, the computer assumes that the files are not erroneous. If it doesn’t match, we get a CRC error.

Without proper aid, compressed data within a ZIP file suffering from CRC errors are almost inaccessible. To regain access one has to fix the error using an appropriate repair tool.
