Make CRC much more automatic

[gth]

CRC-based functions need to be more automated -

* Option to automatically calculate source CRC during copy (after all, you're already reading the whole file in order to copy it)
* Use CRC to verify if the same named file in the destination is in fact the same as the source (various copy operations by other products will 'create' the destination object, but fail to finish copying all the data).
* Automatically flag any failed CRC comparisons as requiring a copy operation
* Upon completion, automatically calculate destination CRC and flag any failed comparisons for possible retry
* An option to automatically retry any file that fails a CRC check

Hi, there's an option in ViceVersa PRO called Verify copy operation by checking CRC: after each file copy operation is completed ViceVersa verifies CRC of target vs. source. Selecting this option will slow down the copying process, because each file has to be re-opened and re-read to be verified. (to verify you need to re-read from target to make sure data was correctly copied)

There's also the option to use CRC comparison to compare files (profile settings -> comparison in ViceVersa PRO). Again, this takes longer as the file contents must be read.

Appreciate the quick reply.

Once those options are set, is the copy automatically retried based on CRC mismatch?

Hi, if there's a mismatch in CRC and error is reported and the copy can be retried next time.
