Those are correct.

You should also have a folder called ITP-Series, that contains more files.

This folder and the two XML files should all be in the root of the USB.

Also note that the 1.40 version of the SMT-6021 SW is very old.

Samsung have released numerous "test" versions of this software to fix EHS and other issues.
I don't know if these "test" versions were issued in the US, but they were available in other territories.
