Hi!
Thank you for the idea.
However, it all depends on the files. Some "read-only" files can be protected by Apple, they can come from cloud music apps like Apple Music or Amazon Music etc. You can send us your log files (https://www.copytrans.net/support/preparing-log-files-to-contact-support/), and we will see if something can be done in your case.
Best regards,
CopyTrans Team
