ATF %dir% field help

[joeconstantine]

I'm looking to update my current ATF string to include the folder that the mp3 is stored in. I assumed this was %dir% or %parentdir% but neither of them seem to do anything.

Here's the string I'm trying:

[%artist% / ]$if2(%title%,$filepart(%filename%)) // $if2(%album%,%dir%)

Thanks in advance.
