Sonar X2a : Figuring out 32 Bit & 64 Bit Plug In Directory Management

Below is the default directory installations for my 32-Bit (x86) and 64-Bit plug in installations. I'm contemplating attempting to re-organize these into two master folders. 

VST (32-Bit)

VST (64-Bit)

Some have suggested four master folders as follows: 

VST EFX 32

VST INST 32

VST EFX 64

VST INST 64
