What's the difference between these, and what's the ordinal ranking of superiority for duplicate file detection and deletion?
Is there a way to ID corrupted files to flag for deletion?
MD5 vs. CRC32 and Byte by Byte Comparisons

DV
MD5 and CRC32 are way of fingerprinting a file. With any method like this, there is a small chance that two different files produce the same 'fingerprint' or hash. With CRC32 there is a reasonable chance this may happen on a large pool of files. With MD5 the chance is so small as makes no odds.
Byte by Byte actually compares the contents of each file to one another, "Byte by Byte". This method is foolproof, but a lot slower.
Duplicate Cleaner uses fast 128-bit MD5 hashing.
DC doesn't currenly have a check for corrupt files.
