For the rest of the files it returns 16x16 and the requested size. If low size is not set it is assumed to be 16x16 so we can omit setting it.

I can't see anything about that in the documentation for [`IExtractIconW::Extract`](https://docs.microsoft.com/en-us/windows/win32/api/shlobj_core/nf-shlobj_core-iextracticonw-extract) which says:

`nIconSize` - The desired size of the icon, in pixels. The low word contains the size of the large icon, and the high word contains the size of the small icon.

For the return value, the documentation says, _“Returns S_OK if the function extracted the icon, or S_FALSE if the calling application should extract the icon.”_ We don't even check the return value.
