What's the difference between a file and a rasp?

Across the reviewers we read, the consensus is that files have finer, milled teeth that smooth and finish metal, wood, or plastic, while rasps have larger, individually raised teeth that hog off material fast and leave a rougher surface. Specialist woodworking communities note that rasps are for shaping and quick stock removal, while files handle deburring, edge smoothing, and finishing.
