>>1488053>RAR recovery record to repair errors or file corruption>Explain this to me. Does 7zip have it too?No, 7zip does not have the ability to repair corrupted files or situations where data dropout on the storage media has occurred. RAR can repair both situations provided that some overhead was assigned for Recovery Records at the time of compression.
It is possible with some file manipulation to try to recover part of the 7zip archive if the file becomes corrupted or has dropouts. See the following:
