DySFV is a sfv checker that's built to give a better visual control over many sfv files at once, instead of just rampaging through them. DySFV can read .SFV documents in order to check the integrity of files.
It works great one one file at a time, but was made for use with large quantities. Also has a clone finder that uses the same CRC32 function.
