SampleTank 3 - which version do I need to keep

[fbenn1]

Hello,

I own SampleTank4 MAX and I know I don´t have to install other versions of SampleTank4 anymore.

But I am not sure about SampleTank3. Do I have to keep old libraries?

In the IK "user area/my products" page there is only one ST3 version listet: SampleTank3 SE v3.7.3
But I have downloaded/stored another library in the past: SampleTank 3.7.3 CS

Can I delete the CS version? Or is that content I still need?

Any help is appreciated!
