Reading the entire file from disk will be very slow on large files, especially video files that can be several gigabytes in size.
Would it be sufficient to only calculate the checksum on parts of the file, like the first MB or so?
Would parallelizing the checksum calculation speed up the process or is it already bottle necked by IO?
