In this picture, "audio" is the
parent, and artist/album, disk location, file type and play stats are its
children"audio" (the parent) has access to every media file in your library, but if you right click on it and choose edit view scheme, you will see that step 4 states
media type: audio, which is why you only get audio files when you select it.
All of the other audio viewschemes (audio's children) will will use the their parents "step 4" rule if that honor parent option is ticked. unticking it, and then applying your own [media type]=audio rule in step 4 for that viewscheme as you did ammounts to exactly the same thing.
Remember, all you're really doing is applying filters to your whole media library. In this instance, there's no right or wrong, just different routes to the same destination
Re. your new problem.
That "use assorted..." option is only going to work for albums MC is already recognising as "(Multiple Artists)"
So, try selecting one album, set it's [album artist] field to (Multiple Artists) and then run the rename from properties tool on that album.
Does it fix things now?
If it does not, then with the same album selected, set the [album artist] field to Assorted, then run the rename from properties tool once more,
but, this time, change the directory rule to [album artist (auto)]\[album] and you should find all your files for that album moved to C:\Music\Assorted\[album]
Once you have a method that works, select all the rest of the affected albums and off you go.
-marko.
(had to rush this a little bit, hopefully it's clear enough)
