Listmates!

I'm looking for some software or strategy suggestions:

We digitize microfilm in house and typically produce rather large and
numerous files as part of that process. We regularly move these source
files from the scan machine to external storage (NAS). We've done this
fairly willy-nilly over the years. I'd like to tighten up this process so I
can be fairly certain that the copy on the NAS is perfect. The machine
creating the files is a Windows 10 machine.

I've looked at Bagit but it seems kinda tedious to use. I guess what I'm
asking is: does anyone have a suggestion for a particular piece of software
that allows copying of files with some form of built in checksum? Or is
Bagit really the best-practice path to happiness? I'd love an open-source
solution but I'm not beyond paying for the just-right piece of software.

Thanks in advance for your help!
