Good morning,

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.

How many of you employ checksum files to verify digital copies over time? What checksum level do you use and, what do you do with the checksum files, do you keep them with the digital copies, elsewhere, etc?

Thank you.
