Thanks MrC but your way above me there. What are expressions? Are you referring to a folder for various artists discs?
MC's Tools > Options > File Location > Audio provides a way for you to specify paths that are used when MC creates new audio media. By setting your paths here, you can be sure to get consistent file locations and names when ripping and when performing other activities where MC stores audio files.
These paths can be static, or can be more dynamic, based on metadata templates such as [Album], [Artist], etc. Still more powerful is using rules to define where media is stored, based on the metadata.
The salient point is to define the File Location values first, and then rip. At the bottom of the Rename dialog, you can also call up these File Location values with the Preset button.
