Windows software to sync files between hard drives

Hey folks,
I’m working on some photos on an external SSD, and when I’m done, I want to copy just the modified files to an external HDD without transferring all the other ones. The file count is getting pretty big. Is there any Windows software that can sync the files between the two hard drives and only copy the ones that have changed?

If you’re okay with using a command line, Robocopy is a great tool for this and it’s already built into Windows.

SyncFolder is a more recent option, or you can use the well-known Synctoy. They are only able to sync edited files.
