Buy an Windows :huh: :rolleyes: - sorry, no idea what's going wrong

See "Mp3tag Options/Directories/Directories" and set "Subdirectories" to "on".
Tell us what happens within Mp3tag list view.

If you select folders in a Windows "folder select" dialogue, then this dialogue shows only folders as objects and no files - if that is your problem.
If you want to get individual files into MP3tag, you have to use the explorer and drag&drop them into MP3tag.
