Trying to verify that copied files checksum-match source files

I copied large number of files from one NAS to another using robocopy command. Several power outages happened during this process, so I wanted to verify that the target files match to the bit against the source files, and Gemini recommended TeraCopy - and I purchased it.

So I set up the source path (let’s say \\A\B\C) then the target path (\\E\F\G\C), where the C folder on both NASes contain exactly the same set of folders and files.

Then I say Verify (with the options set correctly), and yet when I run it, it always says “No Target File” for each file in the source folder.

What am I doing wrong? When I am in the Browse for the T, I can see all the folders under “C”, but i don’t see any files. But this is also the case when I browse the Source yet TeraCopy can see all the files there.

Finally, again upon Gemini advice, I tried to run the command line: This is on Windows 11. There I get a blue error pop-up box which says “This app can’t run on your PC (to find a version for your PC, check with the software publisher“ - and now the TeraCopy installation is messed up, and I have to reinstall it.

I hope someone can help, thank you.
