Hi!

Dear Phil!
Please teach me to use your program in BAT file in Windows.
I can't use for instance %f parameter.
I've tried to use it in many your examples, but Windows allways sees "f.jpg" in parameter "%f.jpg".
For example in command:
exiftool -k -b -ThumbnailImage>"%f.jpg" *.cr2
or without commas
exiftool -k -b -ThumbnailImage>%f.jpg *.cr2
Exiftool gives me one file "f.jpg" which contains all thumbs from CR2 files from active folder. I've decided so because the size of this file is seems to sum of all thumbs.
Command
exiftool -k -b -ThumbnailImage>1.jpg 1.cr2
gives me correct thumb with name "1.jpg". But it works only for one file.
Command
exiftool -k -b "-ThumbnailImage>%f.jpg" *.cr2
gives error: Warning: Tag 'f.jpg' does not exist - IMG_1593.CR2
I've tried different variations but can't find the correct one.
May be you would be so kind to help me.
Thanks in advance,

Igor
