Run into error “Some of the files were not copied to the iPhone



I need help with this, what does it mean by this "Some of the files were not copied to the iPhone because iCloud Music Library is enabled on this iPhone." I've been trying to download a song onto my iPhone 7 and I've tried everything but it still keeps saying. Please help.

- Question from Apple Community

Some of the Files Were not Copied

Why did “Some of the files were not copied to iPhone” occurred?

As the case above shows, some users get the error “Some of the files were not copied to iPhone because iCloud Music Library is enabled on this iPhone” when they sync music to the iPhone with iTunes and they also claim that there are 2 forms of the question:

  • Some of the files were not copied to the iPhone because iCloud music library is enabled 
  • Some of the files were not copied to iPhone because they cannot be played on this iPhone

Cannot be Played

This may seem so weird to many users and they don’t make sense of what has happened. Generally, the reasons for the error can be concluded as follows:

✎ iCloud Music is turned on. Actually, the issue mainly occurs if the songs that you are trying to sync with iTunes are present on your iCloud Music Library. Thus, it won’t be transferred to your iPhone again. For this case, it’s better to disable iCloud music temporarily. After syncing, you could enable it.
✎ Authorization error. You may meet with the issue “Some of the files were not copied to iPhone” if you didn’t authorize your computer.
✎ iOS version. If your iOS version is not the latest one, then the error may appear, too. For this reason, you’d better check it by going to “Settings” > “General” > “Software Update” to see whether it is the root cause.
✎ Incorrect format. For “Some of the files were not copied to iPhone because they cannot be played on this iPhone”, it’s probably related to the wrong format. iPhone works for many formats, however, some formats like WAV files cannot be played successfully on iPhone because the size of it is usually too large.
