I can't delete the Slices Group Name under the Photoshop section

[ozz]

When I try to edit or delete the Slices Group Name under the Photoshop section in JPEG metadata, I encounter the message:
"Warning: Sorry, Photoshop doesn't exist or isn't writable.
Nothing to do."
What should I do?

Can you share the exact command you are using?

If you run the command : exiftool -PhotoShop:SlicesGroupName <filename>
can you show the output?

I you check on the Photoshop tags page, you will see that the SlicesGroupName isn't writable. The only way to remove it is to remove the whole Photoshop block.

exiftool -Photoshop:all= file.jpg

Edit: I just got an IFTTT alert for your question on Reddit. The /r/Exiftool subreddit has only 7 people subscribed and only 5 questions (3 with no comments) in the year since it was created. I wouldn't call it a functional subreddit.

Thank you for your answer.

I will be using these JPEGs for commercial purposes. Is there any risk of damaging the JPEG or its printing process if I completely remove the Photoshop section?

Here is an example of a JPEG's metadata.



I think the X-Y resolutions section is important, but they are already included in the EXIF section, right? So, I assume nothing will happen if the ones in Photoshop are deleted.

The image data of the JPEG will not be touched.

In regard to the resolution tags, you would have to test it. There's no way to guarantee that whatever program is used to print the file will read a specific set of resolution tags or not.

Thank you. One more question.

Instead of specifying the name of a single JPEG file in the code, I want to apply the same operation to all JPEG files in the same folder. However, I couldn't find the code I need to write. I saw the "...\*.jpg" syntax, but it doesn't work. What should I use instead?

Use just the directory name and the -ext (-extension) option

Use a dot for the current directory
exiftool -Photoshop:all= -ext jpg .

Or a full path
exiftool -Photoshop:all= -ext jpg /path/to/files/
