Thank you for your reply!
I think it means “compare two similar files that exist in the automation project”.
The original question wanted to say “compare files that exist in two projects”, so unfortunately I couldn’t use it as is.
However, after thinking about it again, if I copy the file of one project into the other project folder with another name,
I realized that it can be used as a comparison target.
It’s a bit time consuming and not smart, but I’d like to check this out for now.
Thank you!
