Back in 1985 Central Point Software released a disk backup program called Copy II for the Commodore 64 that had some extra utilities for computer housekeeping chores.  One of those was a fast load program called Quickload.  The unusual thing about this fast loader is that it's a two file utility which probably made it unpopular for throwing on a disk full of games or whatever because others wouldn't be sure which file was the loader shim, although the file size probably makes it obvious to the more astute.
