Thank you very much!
This indeed is exactly what I have been looking for.
I know, it is meant for single files only. Most of checksum utilities provide the checksums only.
Some may also provide filenames as well, but further details (size, date) are missing.
A tool like HashMyFiles is putting the details side-by-side, without fieldlabels so to say
(Filename, Size, Date.. etc)
Many thanks again!
