Without a slash on the source directory means copy both the source directory, and the contents (recursively if specified) to the destination directory while adding a trailing slash means only copy the contents of the source directory, recursively if specified, to the destination.

There’s no difference on the DES. A slash on the destination directory appears to have no effect.
