Quite a few times, while trying to open a zip file, you may see a message stating that the zip file is corrupt, incomplete or damaged, and that the extraction cannot proceed. This can also happen if the download is incomplete or has got corrupted along the way.
This happen because Zip files have a well-defined structure and are therefore prone to corruptions. Even in the case of a minor corruption, the extraction tools will not be able to extract its content, since all zip tools first run a check for integrity and if they find that the CRC values of the original files of an archive do not match the extracted ones, they will not work.
