Location of preference files and database on MAC OSX

Hello,

I recently reinstalled Mountain Lion and because I have a backup of all my files I easily recovered all my desired preferences and libraries for various applications. Unfortunately I could not do the same for Soulseek QT because I did not find any system files besides the preference file in /Library/Preferences/

I want to know where does soulseek store all it's settings and index data. Imagine that I had dozens of users and quite a long user info and all of that is gone.

This will help me immensely and every other user out there that needs to reinstall Soulseek or their OS.

Thank you very much!
