Some of the files I get from Google Takeout are named like this:

[UNSET](17).jpg

When I run exiftool -@ use_json.args <takeout_dir> it fails with this output:

    1 directories scanned
   27 files failed condition
    0 image files read

I believe this condition in the use_json.args file is not passing as a result:

# Check if the corresponding JSON exists
-if
(-e "${Directory}/${Filename}".".json")

Is there any way you could adapt to manage these?
