TestName Tag Not Found

[savvypete]

Under 'Writing "FileName" and "Directory" tags' Phil says the smart way to check the file name is to write TestName first to see what the names will be as per:

exiftool -d %Y%m%d_%H%M%%-c.%%e "-testname<CreateDate" DIR

However, I get:

Warning: Tag 'testname' does not exist - New folder/IMG_1532.JPG

How do I generate the TestName tag?

Thanks

Try updating to a more recent version of exiftool.

Thanks, Phil

Works perfectly after figuring out all the %'s in windows! More fun than the Saturday NYT crossword!
