Fuji 18-55 Lens Firmware Update Question

I just downloaded the update for the Fuji 18-55 kit lens firmware v3.24 dated 09.29.2022 from the Fuji site.
It downloaded as "XFUP0004.zip" The zip contained two files
XFUP0004.DAT, 385kb
XFUP0046.DAT, 509kb

So far I have only updated Fuji bodies not lenses no not sure what their update files should be. I would have thought one ".DAT" file.
The fuji site makes no mention of two files

Does this look correct and if it is which file to use?
