We use Toast442.org's MD5, http://www.toast442.org/, to run our
checksums. It is free Windows software and works rather well from our
perspective. We have used it for about 3 years. All checksums
generated are kept in the folder containing the digital files and is
named so that we know exactly what it is for. In our case, we give
everything a batch number, so the checksum is saved using that
particular batch code. Should the data in folder change, a very rare
occurrence, the checksum would be run again.
