There is no direct comparison of files from within mp3tag. There was a discussion some time ago with a potential way to try this. Maybe it can suit your needs.
thx alot, i think now i got the point.
but what's a bit of a trap is, that all top directories are also included in this list, i.e. a, b, c, d, .....
so this playlist makes mp3tag to load all subdirectories also
but if i switch off subdirectories in the options then it works .....
2morrow i'll check the rest, but for this, THANK YOU A LOT, i really know how much programming and debugging effort this must be.
cheers
