RapidCRC Unicode is an open source file hashing programs.
This one is perfect for a particular use case I have. I can point this utility at a directory, and it will recursively hash all of the files in that entire directory and subdirectory structure. Then it will output that to a text file that contains the path and filename of each file along with the hashes.
I end up having multiple copies of files on multiple drives and other media, and I like to be able to take the output here, throw it in a database, and then be able to look at filexxxyyy.zzz on my hard drive and see that is the same file as filexxxyyy.zzz that is in a 7Zip archive on a Blu-Ray in my office.
