Hello.
I have this code:

Quoteexiftool -ext pdf -overwrite_original -xmp-pdf:Producer="" -XMP-xmp:CreatorTool="" -pdf:Creator="" -pdf:Producer="" -r test\

The fields should actually be empty but two question marks appear. What can you do that the fields are empty?

Thanks for your help.

Use regular quotes ", not fancy quotes "
(or use no  quotes at all -XMP-xmp:CreatorTool= )

The command line treats fancy quotes as if they were regular characters, not quotes.  If you are copy/pasting from a word processor or Google docs, they will "help" you by changing regular quotes to fancy quotes.  If you are on a Mac, there's a setting that "helps" you in this way as well.
* Did you read FAQ #3 and use the command listed there?
* Please use the Code button for exiftool code/output.
 
* Please include your OS, Exiftool version, and type of file you're processing (MP4, JPG, etc).

Note that the quotes are completely unnecessary in this command (as StarGeek mentioned).  Either with or without the quotes, these tags will be deleted since the value is empty.

...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 ($).
