There isn't any "specialized" way of deleting tracks. If you have the old mp3s in their own folder somewhere and they are in the MM library, you can simply go to wherecaptainkurt wrote:I want to keep the flac files and delete all old mp3 rips of those.

they are at Entire Library > Location > right click and remove/delete them in 2 steps (press delete > choose from remove/delete menu).
If they are not all conveniently stored in a separate folder, you may be able to use the Extension and Date Added columns to gather them together.
