December 11, 20169 yr Hello, can you suggested me some freeware program to calculate+compare+store&reuse hashes of 2 folders? (plus subfolders) I need this to check multiple backups on various HDDs. For now I found "Checksum Compare" (even if the official website seems ko). It's very good, but a bit clunky and doesn't allow to automatically store&reuse the correct hashes.

December 12, 20169 yr Get hashmyfiles:http://www.nirsoft.net/utils/hash_my_files.html save the hashes for the two folders/structures. Compare them with a text comparing tool. Or - maybe - Exactfile:http://www.exactfile.com/ The general idea of both is however different, you first hash the "original", saving the hashes to a "digest" file, and then hash the copy comparing its digest to the former one, unlike the "dual pane" view you have in "Checksum Compare". jaclaz

Thanks for the suggestions, even if.. I'm not sure they're much more convenient.. CC already allows to manually save the results, but I wanted something more automatic. Oh well, maybe I could just diff the CC ones.
December 12, 20169 yr Yep but both accept command lines (or for exact file there is a command line version), you write a three (or four) line batch and you are all set off. Specifically exactfile command line version can do the comparison against an existing "digest" file: http://www.exactfile.com/exf/exf-command-line-usage/ jaclaz

I'm trying the command line version of Exactfile and it seems good, even if.. it's still in Beta since years. Thank you jaclaz. --- Some minor annoyances are that: - it doesn't have an option to output a duration\end time or a % progress. - it uses a space as a separator between hash and path, instead of "tab".
