Checksum manifests can be a helpful digital preservation tool when attempting to check fixity on a large group of files. For example, one way to ensure that a corpus of files are successfully copied from one location to another is to create a checksum manifest of the files before transfer. This manifest can be compared to the checksums of the new copies in their new location. If all has gone well, the copies will be identical and therefore the checksum manifests will also be identical. That same manifest can then be stored and used to ensure that no changes have occurred to the files since they were created.
