I have added a tag to my classical music FLAC files to identify a specific "Work", so I can have a view which selects files by "Composer", then "Work" then "Name." This works fine on my home network, but when I copy my files to an external hard disc for use when I have no internet access the "Work" tag disappears. I don't want to have to recreate a "Work" tag in the files on the hard disc, so how do I make sure the "Work" data is embedded in the files when I copy them over?
Any ideas please.
