Samsung PC Studio 3 and SGH-a437


In Runtime
I am using Samsung's PC Studio 3 for Windows XP and i can transfer audio and graphics to and from the phone (SGH-a437) but I have read online that to transfer .jar (along with it's .jad) files you need to place them in the "Other" folder. On mine, I do not have an "other" folder. All it shows in the tree is:

My Phones
Ringtones Audio
Temporary Folder

How can i transfer java files to the phone? I know it supports java because it has games like tetris and a mail app that were written in java.
