The only differences are that my file is called ‘Library.xml’ but not sure why that would make a difference – maybe the space in the name is throwing things off? And my ‘Library.xml’ file is placed inside the Media folder.
So, you have This Mac/Samsung T5/Muziek/Music Library.xml
I have This Mac/Media Library (my external hard drive)/Music (this is were the actual files are)/Library.xml
So the Library.xml file is saved to the same level as the actual media files. In your set up I’m assuming your media files are sat in the ‘Media’ folder? Try moving the Library.xml file to that level.
