[dede]

Hello, I use a batch file whith a "for in do" which travel all the folders of my computer and i want to delete all the metadata of all pdf files.
My probleme is that, i disable with an @echo off the message from the cmd but there is still the message from ExifTool saying for example that there is a file update or there is not files specified ( no problem because i use *.pdf to research) So how can i disable this message for gain time please?
Best regards dede.
