While there is no guaranteed way to fully recover corrupt CR2 files, these methods may help. It is always essential to work on a copy of the corrupted file to avoid further damage. Raw image files, such as CR2, contain unprocessed and uncompressed data from the camera's sensor, making them more susceptible to corruption and less likely to be fully recoverable using common image repair tools.
