That did the trick, thank you!

$If(<Type>=Podcasts,Podcast,$If(<Type>=Audiobooks,Audiobook,<Type>))

Thanks. What would it look like to handle both Podcast(s) and Audiobook(s)?

No, Type is in internal mechanism and not customizable.

It sounds like you're using <Type> in the Auto-Organize Mask and thus should be able to use $If(<Type>=Podcasts,Podcast,<Type>) to still use the same Podcast folder as with MMW4.

It looks like the values available in the Type field pull-down changed from MM4 to MM5. For example, there is no longer a "Podcast" choice but there is a "Podcasts" one.

I use the Type field in my Auto-Organize destination, in the path. That means that I have thousands of files MM4 organized into a Podcast directory tree; and MM5 moves new files to an identically-structured Podcasts directory tree.

I'm really not keen on moving the files organized by MM4 to match where MM5 now wants to put them. Is there some way to edit the available Type values?
