When compressed file does not unpack correctly in .zip or .rar extraction we get error or warning saying
F:xyz.zip:CRC failed in xyz file. The file is corrupt
If file size is small than you can try to re-download it.
Otherwise you can try to extract file by ignoring errors.
follow this steps:
2) select extract files
3) in Miscellaneous options check “Keep broken files“
In most cases this method works just fine.
