Good morning,

We use's MD5,, 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.
