FujiFilm X series cameras have started to support the HEIF format

As far as I can see exiftool extracts all the interesting EXIF metadata from these files

But I can't seem to find the correct command to extract thumbnail images

HEIF files have thumbnails but not in the same place as JPEG files and exiftool -ThumbnailImage doesn't find anything

(actually the FujiFilm files appear to have three embedded jpeg format files of differing sizes)

Using exiftool -v3 <HEIF File>.HIF shows that exiftool is finding the thumbnail but I can't find the correct command to extract it

Is this possible?

...where DIR is the name of a directory/folder containing the images.  On Mac/Linux/PowerShell, use single quotes (') instead of double quotes (") around arguments containing a dollar sign ($).

I got it, thanks.  I can see what looks like JPEG previews in the file...  I'll work on adding the ability to extract these.
