Is there a way to see what Robocopy copied after I closed the CMD window?

Unfortunately, if you didn’t set up logging with Robocopy, then you won't find any logs laying around. However, if you rerun the same Robocopy command, it usually picks up where it left off, depending on the options you used. Just remember to enable logging next time!

If you didn’t run with the logging parameters, that’s a tough break. Robocopy won't automatically save logs. I’d recommend checking for new files using Event Viewer, but it won't track what Robocopy did before the CMD was closed.

When I have to redo a copy, I use the overwrite switch to make sure everything is correct. Just be cautious; an interrupted transfer could leave files in a questionable state. They might seem fine, but I'd double-check.
