Where are WEKA installed packages stored I would like to use the WEKA library in a Java program but I can't seem to find the methods I installed using WEKA's package manager. 

Does anyone know where the installed methods are stored?

For clarification, I installed WEKA, installed the extra package using WEKA and can use it with the WEKA GUI. But I can't find the installed package in the .lib file.
I don't know how WEKA stores the extra packages on other installations, but for my Windows 10 with WEKA 3.8 it was here:

WEKA stores the extra packages in a direcory called packages. This package was in my user directory and under the wekafiles folder. 

Example: "C:\Users\myUser\wekafiles\packages....."

Hope this helps someone else.
